Cheers I have found and ordered the correct mcb I will get an electrican to rectify and fit the mcb
What was wrong?
Who did what was wrong?
When you had the electrician there why didn't you to get him to sort out the garage lights?
I wold like some advice on lighting my garage has a florescent light on the celling there is also a light outside the garage when the garage light is switched on the outside light comes on as well both lights are wired to wall switch which I presume is a 1 way switch
Presume??
You installed the switch:
I have hager fuse box I fitted a new light switch in my garage
so why don't you know whether it's a 1-way or not?
Do I need a 2gang 2 way switch
No - unless you want 2-way switching you only need a 2-gang 1-way switch, but you can of course wire a 2-way as a 1-way.
I would like to know where the brown and blue wires of the lights would be connected
Well not both to the switch, obviously!
The best advice anyone can give you is to go away and get a decent DIY and/or home electrics manual and learn how circuits work.
Given the questions you're asking you don't yet understand the most basic facts about current flow, what the difference is between live & neutral, or how switches work.
Thinking you can dive in and start doing things, asking questions here when you get stuck is a dangerous and very inefficient way to learn. You can learn what you need to, but until you do please leave the doing alone, as you should not be wiring things up on a painting-by-numbers style following of instructions to put this colour wire into that hole - you must actually
understand why, and what's going on, and how it works.
