Thank you for the video! In the United States all new construction, all main panel residential replacements must include whole whole house surge protection devices per NEC code.
I was a bit confused by your explanation as you show the SPD as in series with the load and shunting over voltage between line and neutral. Type 2 SPDs are parallel devices with the circuit and shunt over voltage to earth and your actual CCU wiring shows this. Also you keep talking about "ring main" when referring to ring final circuits.
Thanks for watching. This was an early video for our channel so we have definitely taken your feedback. We may do an updated SPD video to clear these points up. Thanks again
Great video, very informative. The one thing that's always bothered me about SPDs is you could fit one today and it could be wiped out tomorrow and no one would know. Its like having a smoke alarm that doesn't beep when the battery is low or ran out. They need to get these things audible or somehow integrated, for example if they absorb a few surges and the flag goes red then your lights trip or a contact trips and produces a loud buzzing sound. I don't know... but somethings got to change.. probably hundreds of people sitting at home right now with blown SPDs and haven't got a clue.
Great point. It’s like RCBOs and RCCBs though, the occupant is supposed to do regular tests and and SPD is included in this by way of visual check. We all know this hardly happens and that the occupant only goes to their “fuseboard” once they’ve tripped a circuit. We believe electrical safety is something that both the governing bodies and government should be working harder at, to educate the general public. This would also protect a lot more homes against risks of fires etc
The company I work for sell them with contacts for alarms. The only problem is the end users would soon get fed up with a buzzer going off until the electrician comes out. You could have light I suppose. It would have to be where someone notices. it. Lots of companies produce these with alarm contacts now.
SPDs and AFDDs are a good idea in high risk installations but not domestic as they don’t work . A number of people have done videos were they tried to get them to operate and the domestic circuit will not create a high enough serge or high enough arch volt . In my opinion theses things would be great for cocker and shower circuits but on a 32amp ring main witch will never draw any were near 32 amps they will just sit there until doomsday doing nothing This is just an sails rep trying to sell his products, but who am I to argue i’am just a humble spark who’s opinion means nothing.
@@JoannaHammond not needed across the hole board also if they do work then they will all trip plunging your house into darkness , but I could be wrong on that one.
SPD's and AFDD's are two completely different things, so to say that neither are useful in a domestic setting is wrong. Of course you being a humble spark I'm sure you will have educated yourself on the differences between the two and when you should be installing either device and why
This demonstration is showing an SPD being installed in series with the theoretical ring circuit. However, an SPD is installed in parallel within a consumer unit. TBH im confused.
You right they sell them for profit. SPDs are useless in dwellings. This guy done series of videos about the issue ruclips.net/video/YgDkXfbUzek/видео.htmlsi=JqFy2TAogZ45Xdih
Due to their nature, you get complaints like "My TV doesn't work it was destroyed by a surge and I had surge protection." No one ever checks then. The SPD could have failed a few days after installation. Most other items in a consumer unit are fir and forget. SPD's aren't
It would be nice to see the physical and Scientific eve dance that prove these things work and are necessary in domestic installations . But the evidence doesn’t exist. Show us the evidence .
@@navitascp BS7671 does not have or show any evidence, there is no evidence scientific or physical .also BS7671 is not mandatory , in any shape or form . So stop talking bollocks and get your facts right. You’re just another sales rep trying to make a sales pitch in order to sell your products.

Thanks for watching 👍🏽
Very educational and simplified. Great Video will. The double camera worked well. Look forward to more content
Thanks for such a great lesson, however I would like to know whether the spd can be of help to a circuited breaker in the event of a fault
Thanks. No it doesn’t not disconnect a circuit or detect a short circuit or earth leak
Great video, thanks.

Where and how do these over voltages come from?

@@navitascp Wow, I am an unusual client then. I check my RCBO's about every 3 months and I check the SPD to make sure it's green as well..... :D

Isn't that why you put them across the entire board? So they cover everything. Not a spark, just asking.

This is correct! Electrical safety awareness is definitely something the tenants and home owners need to me re-educated on as well
Thanks for watching
I was interested in the subject, however the redundant use of "so" grated to the extent of abandoning the film within twenty seconds
Changing camera view ( not necessary) gesturing with hands very distracting to actual contest.
Thanks for watching

Show us the evidence .
Thank you for watching. The science and evidence can be found in BS7671 and is now a mandatory regulation

Blast 500 volts through one then tell us they dont work😂
