Hi,
I am looking for a device or way of protection single phase 220v equipment from overvoltage.
There is a device AVS30 from www.sollatek.com that does this, however if the voltage is above 320v then the AVS30 is itself damaged.
Is there something that would protect up to 400v.
thanks
John

When the origin is a TNCS and you are running to say a shed/barn which you are going to make TT. Which do you use to protect the sub main run the TNCS or the TT?. I’m thinking it’s the TT earth you use to protect the incoming cable. What do you guys use?

Hi all,
A customer doesn't want a new consumer unit, but wants work doing to an existing lighting and existing ring circuit.
I believe I'm correct in thinking that if I do work on these older circuits, I must then RCD protect them. Is it better to fit an RCD to the incoming mains, before...

I know that you can put one in a single module enclosue next to the board, but can you protect the whole board?, its just the wiring configuration im not sure about, do you have to split the supply in a henley block, or just route...
I am quoteing to change an old consumer unit to 17th edition on a TT installation. I have checked the regs and it looks like the preffered option is to give added protection by changing the 100A main switch to a 100A 100mA RCD together with the 30mA RCD protection already in the board. Firstly...

hi, I always use conduits when running cables for sockets and switches but some of my mates say you dont need it and cables can be burried straight under the plaster without conduit. Are they wrong or right?
in a t.t system i have all way thought you need a 100mA s type dp rcd covering the whole installation
been to a job today and it is a standard board dp isolator and filled with rcbo's which yes they will protect as for high earth loop but they are only single pole am i right in my thought's
