Have to replace this old board for a elderly relative of my soon to be wife, British Gas have been along and used soem of the special triangle stickers to say it is unsafe - but still fitted the new boielr anyway with a FCU from the socket circuit in kitchen, as always money is the priority for them. Somebody else went through effort of putting fairly recent stickers on the oard but didnt fill them in either.
Got me thinking though, I have as yet not been able to locate the earth rod, Zsdb of 26.3 Ohms with water and gas bonds disconnected so potentially an Ra reading.
. there is a bonding to water, bonding to gas and a 3rd cable that disappears off into the wall not with the tails!
So may need to add a new rod to be sure as its all TT around this rural area.
So looking at the board it has 100mA RCD protection as the main switch but why fit just this, why not have a 30mA RCD main switch? especially given the circuits have no other RCD protection.
was this common practice back when this was fitted when the house was built? just seems a strange way of doing things. could be done to 15th maybe 16th edition? before my time eitherway.
Thoughts?
