In 2018 We had lightning strike a tree in our backyard about 25’ from the house. It traveled across the ground, blew a small trench in the dirt across the yard, arced on the metal astragal on the French door in our basement that I was standing 5’ away from, blew the ramset nails off the wood piece under the door threshold. We had WHSP on both panels. We lost all the TV’s, AV equipment, garage door openers upstairs on both garages, a fridge in the garage, a ceiling fan on the opposite side of the house on the 2nd story furthest away from the strike, the LED string lights on the back deck, a remote control switch for my dust collection in my workshop, an HDMI cable (had to cut open the ceiling and re-fish a new one because the old one got stuck on something grrr), and the main control board on our Trane Heat Pump in the basement. It was totally random the things we lost and didn’t lose.

SPDs operate by passing CURRENT to (ground, neutral, common) which reduces the VOLTAGE due to the resistance of the source. The rating is how much current they can handle. The combination of voltage, current, and time is energy (joules). Again, the rating is how much energy they can bypass or absorb.
@swansontec
2 жыл бұрын
I wanted to say the same thing, but you beat me to it. The SPD works like a switch. When the voltage is normal, the switch is off and no current flows. When the voltage is too high, the switch closes to intentionally create a short-circuit between hot and neutral. This adsorbs the energy from the transient event, converting it into heat inside the SPD. Energy = voltage * current * time, so a higher the Joule rating means the SPD can short more current for a longer time. The voltage should stay constant if the SPD is doing its job.

Hey, just a homeowner here, not electrician, looking for some clarification. Dustin mentioned certain high drain loads like a central ac that strains the system could have an effect on other devices in the home over time. If I were to install surge protected breakers on the large appliances in place of regular breakers, would this protect the other devices and breakers in the home or does that only protect surges coming in from the service line to that particular breaker? Thanks in advance.

There are 3 types of non desirable voltage fluctuations as follows. To start with we normally get a 120 VAC (RMS) 60 Hz sine wave. A surge is when we have condition where the RMS voltage of the mains increase past the nominal 120V. An overvoltage surge typically lasts for several cycles or even minutes. The second type is spikes. These are short term (ms range) high voltage transients that are only present for small fraction of a cycle. The last type is EMI/RFI interference. These are typically low voltage high frequency waveforms that appear in addition to the 120 VAC waveform. These can extend right up into radio frequencies. All electronic devices should contain circuitry to filter EMI/RFI interference and it has very little impact on power equipment. The types of protection that are needed against Surges and Spikes are completely different. Obviously you cant have a piece of equipment that cuts power every time the waveform slightly rises otherwise stuff would continually be turned on and off. Instead surge protection will kick in after a few wave cycles. A spike by its definition is very short term. If one was hit by a very high spike say 10,000V the event will be over before a surge protector can act. Spikes must be acted on and very quickly (typically in mS or uS). Some electronic equipment contain basic spike protection. What they do is run the AC lines on the PCB near a ground line. When the voltage rises on the AC traces it will arc over to the ground line dissipating the energy. For those of you who think that power bars provide adequate spike protection think again as most are useless against a high voltage transient. ALso dont fall for snake oil salesmen trying to sell you power conditioning equipment for your home audio, a complete waste of money. Most spike protectors work by dissipating energy in a spike. This is why they are rated in Joules. I live in Canada and my experience is that power surges that damage equipment are pretty rare. The only one I can think of is when a utility installed the wrong transformer and people got a much higher voltage deliver to their homes. The utility paid damages in that case. Spike damage I have seen and usually it is because the dissipating/switching device has failed. EMI/RFI are annoying but not damaging.

exponent mantissa, you are absolutely 100% correct, unlike electrician U in this video. It is essentially important to know the DIFFERENCE between surges and spikes, as you have described above, as well as the Joule rating of the protective device, to get the protection you actually need for sensitive devices. If your device needs SPIKE protection there is no reason to purchase any but the (misnamed) "Surge Protector" with the HIGHEST Joule rating. Another source of over-voltages, or surges, is an open neutral wire in a residential 120/240V system (common in the USA). The 240V remains the same but the two 120V "legs" fluctuate up and down as loads are turned on and off, often resulting in burned out equipment and house fires. Open neutrals do not threaten the building's wiring unless the building burns. The Utility is usually responsible for "open-neutral" damage and may try to duck that responsibility by claiming the neutral - ground connection was faulty or the devices were not "surge protected" which is actually "spike protected." Neither of these are actually relevant to the over and under voltage "surges" caused by open neutrals. As an expert witness forensic engineer in many disputed cases, by understanding the difference between surges and spikes, I have caused the Utility company to pay for their open-neutral damages,

Hi Dustin - Electrician U! I liked this video and wanted to say that you are right on! I get a lot of emails from people and everyone contacts me all the time asking me about portable surge protector power strips and what ones are best for lightning protection and what people do not seem to fully understand just like you as well were saying in this video is that a surge protector is not lightning protection. A surge protector can sometimes help from light surges from far away from lightning that might come through the lines but not direct strikes as you and i know. I also get a lot of people contacting me asking me by one of my videos on my youtube channel videos why i was saying its so important for people to replace there surge protector power strips every 3 to 4 years and people do not seem to understand that either how even if the Green LED lights that say Grounded & Protected are still lit that it does not mean that people are still getting full surge protection anymore and surge protection power strips are only good for so long and after 3 to 4 years if people do not replace them then they might not be getting the full protection anymore regardless if the LED lights are on or not. Do you ever get people contacting you about that to? Another thing i get from other people is people who think that surge protectors last forever and and are a one time deal however that is not the case and all surge protectors all have there lifetime to. I have told people before how i know that some surge protectors are expensive or sometimes even surge protector power strips to but they are a lot cheaper than all the electronics and appliances Owners have bought and rather than risking destroying all there things to just keep there surge protectors up to date and replace surge protector power strips every 3 to 4 years and avoid damaging there stuff. I also have told people before during severe weather that the best solution for sure is to just unplug any expensive things they cannot afford to lose until any severe storms are over. I was going to see if you want to join in with me and make a video about these topics as well?

As an engineer they are not that confusing. Simply search metal oxide varistor's. It simply changes resistance in the presence of voltage. For SPD's they are chosen so that resistance is about zero below a threshold voltage say 300V past that it becomes more resistive, This causes the excess voltage to be converted into heat. Over time these heating cycles will break the device down or if a spike it too large melt it. This is where the joule rating comes in. The joules of heat the device can soak up because there is a time component to it and how long the spikes are.

In addition to the main panel that the overhead neighborhood supply line comes into the house where the “main” surge protector is, I have two breakers panels inside, one upstairs and one down, the downstairs panel I had a line w two breakers run outside to the chicken coop, so if a lightning strike happened to hit near the coop line, it would go to that downstairs panel (and fry everything that panel provides power to) and bypass the surge protector in the main incoming panel..so, I had an additional surge protector placed into that downstairs panel. The electrician was saying the other protector would still provide protection, (which is dubious) but agreed that it was proper to go ahead with the caution.@@MrsBuddevil

Hi Dustin, Love your video. First of all I am not an Electrician. I just know the basic and that is why I watch video like yours to learn more. I have a question regarding Surge Protector and how some surge protector work. I'm talking about the one you install next to the unit like the AC compressor unit. I saw a video in installing a ICM493 and the connection to this connected is like a series connection. I can understand how it work. The surge will get detected by the ICM493 first before the AC compressor so it can cut off the power to the compressor. But the one that connect like a parallel connection like the ICM518 or the RSH50. Its connected or pigtailed to the L1 and L2 of the wires that goes into the AC compressor unit. Since it shares the same wire, when the line get a surge, it will send that surge to the AC compressor and the surge protector. Can you shed a little more light in how protector like the ICM518 or RSH50 protect my AC compressor. Thanks, Phil

I'm told it was 35K volts. It indeed blew up the surge protector. The result was the computers were fine, but the surge protector was toast.

Could this be because of a voltage dip, which then causes the refrigerators to have an issue? And if so is there a surge protector that protects against dips? Thanks so much!

When I had a Generac 22 kw generator installed a couple of years ago, the company installed another whole house SPD in the automatic transfer switch under the lugs of the customer load terminals. One of the LED's for the L1 is out meaning that the MOV's for this leg are no longer capable of doing their job. The whole house SPD QO2175SB green LED still is burning brightly and therefore this device is supposedly still functioning normally. My question is, do I really need to worry about replacing the SPD with one leg LED being out? I am thinking that I don't need the one which was installed in the Generac automatic transfer switch.

If a surge should occur does the 15A or 20A circuit provide more protection to the Dishwasher? Does the smaller 15A provide more protection for the appliance by limiting the Amount of current/Amperage surge allowed past the breaker?

Type-2 is installed after the main breaker on the service panel and is connected via a 20-amp or 30-amp breaker. also if you have sub-panels each sub-panel should have a type-2 whole house SPD. also and equipment such as an A/C unit with a disconnect should have an SPD installed The ideal system should make use of Type-1, Type-2 and type-3 SPD's. (That's my understanding of what I read in section 242, But I may be wrong)

Dumb question: Twice my buddies house had over voltage event due to a tree falling on a 12KV line which came in contact with a 7KV line that fed his transformer. Blowing apart his class-2 SPD two HVAC's plus. Is there a system that would open the secondary off the transformer fast enough to give some protection?

Here in the UK SPD's are becoming more of a thing, so are Arc Fault Detection Devices but where our consumer units are located most households don't have the room. Here a standard board is a 10 Way containing 10 MCB's for out going circuits and 2 RCD's to make up 2 protection banks, 5 MCB's on each. Then we have the MAIN Switch. So if you add a SPD on the input that's another 2 ways gone or a bigger consumer unit would be required. I realise your electrical Panals are different in the US. Our electrical supply is changing, more local generation from households and industry and even talk of our EV cars becoming a local back feed into grid to take some of the high times of load away. All this is creating more noise on the electricity that's coming into our homes. The problem of noise is being passed onto the consumer to fix as it's another product that be sold. Instead of manufacturing creating poor quality "noise sources", Standards need to be in place to stop this at source.

It's more than comprehensive because there are misconceptions about surge protector especially when people mistakenly use power strips and think it will protect their appliances.

In Russia today on December 22, the holiday of electricians is celebrated. This is due to the adoption of the Russian electrification plan. In 2020, it is exactly 100 years since this plan was adopted 😜😀

There is also high/low or under/over protection.

As service electrician I quite regularly find the DP breaker feeding the in panel surge protector tripped. The service calls are unrelated to surges. Because the status leds are never monitored by the consumer it is hard ascertain as to when the trip may have occurred. I have only had to replace one Siemens unit. All others showed status ok after the breaker was reset. Any ideas?

Although I’m not a registered electrician I am quite capable. Correct me if I am wrong please, if I have only one device and it is electronic in my house, is it more vulnerable than if I have many appliances on the consumer (fuse box) unit along side with it? This is without any surge protection device. Do capacitors in other devices protect against spikes or surges. Many thanks for your video.

Can you provide clarity on the power/line conditioner, a UPS, and their role (if any) in surge protection?

A UPS is a power conditioner with a battery and inverter for sustained power during an outage.

Power/line conditioners are able to take less severe but more frequent fluctuations in the sine wave and smooth them out, for cleaner power better for sensitive electronics. Many UPS’s are able to accomplish this because the take in the “dirty” power to charge a battery, then output from the battery via an inverter a cleaner wave for the device(s) it serves, with the added function of being able to continue to power those devices for a time when power is lost depending on how they are sized. Neither of these would be designed to handle the magnitude of the surges and spikes in this video. Many of the local UPS you might get for desktop workstations would also have a surge protector build into them to handle those.

Can I put a surge protector when I connect a generator to my house for back up? And what is the best

I have an old home, and there are quite a few outlets that are only 2 wire (no ground), which makes plug-in surge protectors useless. If I were to buy one of these SPDs to install in my breaker box, would this protect the devices using the 2 wire outlets from power surges?

For surge protector like Siemens QSPD, from their instruction video looks like it doesn't have to be on the first slot that's closest to the breaker main switch. If there's a surge, say it's installed on far away from the breaker main switch, does it mean those before the surge protector will fry? Or it will go to the surge protector as a least resistant path? How does it work really?
