Domestic Surge Protection/Diverter

Seanbass

Hi all,
was looking around and couldn't find an answer, I was just wondering how exactly do you wire a Surge diverter into the consumer unit,
All my mates I asked had never wired one and I tried asking the wholesaler and he hadn't a clue.
any help would be appreciated!

this is the exact one here,
it is the cartridge type.
Live in top?
whereabouts do I take the live from, just loop in and out after the main switch fuse?

i would feed it off 20amp mcb on its own (not on elcb)just for isolation purposes as it does not take a load
the whole installation will be protected

ah ok, thanks alot man
just to clarify,
take an extra feed after the swichfuse into a seperate mcb to feed the surge diverter and it will protect all circuits?

spot on
10 square earth then to busbar

Seanbass

thanks alot, appreciate it

You sound like a guy with some experience on fitting these, what's the easiest type or make to look for at the wholesalers when fitting in an existing consumer unit? Cheers

straightforward enough
cartridge type
wont disconnect power even if it trips out
just replace cartridge

Hi all,

just using this thread as it seems to match my query. I have an induction hob which on two occasions now has been damaged after power being lost to the house/hob. After power being restored the hob has shown an error condition. The service engineer has been out and its seems different components have failed. The first time it was covered under warranty but now the manufacturer is saying the damage is due to power surges and thus isnt their responsibility.

What has me worried is if i get it repaired, how can I protect the unit from future surges that I cant control, ie there might be esb failures or I might need to turn the power off at the mains fuse box.

Are any of the referred devices suitable for my needs? So if a surge is detected, will a cartridge need replacing before we can use the hob again? Does that mean an electrician is needed? I believe the hob is on a 30AMP circuit if that has any bearing?

Thanks
W.

im surprised damage occurred due to loss of power only(how did loss of power occur and how do you know it was a surge?was anything else affected)
if the surge protector detects a surge and needs replacing an indicator is visible.it will not shut down the power thus allowing appliances to be used,you can remove and replace cartridge without power loss.an electrician will not be required to replace the cartridge if you are instructed how to perform the task

This may help then again it might confuse.

I had another link which said that instead of a branch from the phase to the SPD, the SPD should be wired in a V shape with the phase going in and out of the SPD.
