it needs suitable overload protection. the 25a rating on an RCCD is simply the current it can safely handle, it does NOT offer any overload protection. maybe go get a refund from your short courseI'm using a rccb 25 amp would this be any good or does it need to have its own 16 amp rcd
there should NEVER be a socket to connect to a supply elsewhere. there may be a plug, but a socket is very dangerous, and the lead to attach it is more commonly known as a widow maker. im sure you can figure out why its called thatYes this is not my work it's something that I've came across, it's on the back of some portable toilets . Each toilet has its own 12v light in . All the electric is on the back of the toilets . When these are taken to site the are plugged straight into power via a surface socket on the back.
i still dont have any idea what you are talking about. and as ive already said, an RCD does not give any overload protectionThanks for your reply, this is what I'm saying, they have put power straight into the isolator socket which then goes into the 25amp rccd , I would have thought that the power should have gone straight into the rccd first and the isolator socket should have had its own separate protection .
