No electric in my garage

[Specialist]

It's fairly common for terminal's to loosen & burn after a period of years, your electrician will sort it when the switch is replaced.

That's not an RCD by the way, it's a 100 amp main switch.

Hi - post #43 - its hard to diagnose via the internet, but I think the cable is burnt (looking closely at the blue and red at the base) a sign of overload. In the house fuse board, what's the mcb rating that protects the black cable going to the garage?

 

[Dave OCD]

That is a switch that's overheated and failed not an RCD !

Its the one with garage above it in the off possition.

That's an MCB at the supply end, hopefully that's fed via an RCD in your house Consumer Unit ? The rating would be fine for the cable feeding your garage but with the 3kW spa thing there wouldn't be much spare capacity at all. Also the main switch at the garage end board must have had a loose connection or an internal fault to overheat and fail like that.

Hope this helps.

That armoured is not even properly fastened to the board, get an electrician in to fix those few odd bits we picked up.

 

[Dave OCD]

Yes that's good, some will say not ideal as an earth fault in the garage will cause the loss of the other circuits supplied via that RCD, but the main thing is you have overcurrent and RCD protection for the garage.

Looks like the main switch in the garage is a different make to the mcb's. My guess it's been replaced from a RCD and not made.

Hi im telling you as much as i know all the work so far was carried out the electrician that was hired by the builder that converted the garage or when the house was built.

Should a rcd be there insted of the main switch?.

Honestly mate the best advice we can give you, is what we've already told you: Call in a Decent Qualified Electrician to sort it all out for you Safely.

I think the fact you keep fishing for information after being told you need an electrician in to sort out the problems and test the arrangements as safe to use is making people suspicious. They may be suspicious that you intend to fix the problem yourself, and possibly installed the circuit, complete with faults, yourself.
You can allay these suspicions by calling out an electrician to sort this for you.

This is the wise choice. It is not just a case of swapping components. There are issues to be addressed with the methods of installation and circuits will need testing with the proper equipment and knowledge of testing procedure.
