My Bright Green Lamp Limiter

[Mabo5]

I am going to bite the bullet and say "If you don't know what you are doing with mains electricity, don't do it".  You only get one fatal shock.

That's just it - I've seen a single-bulb version, but when enquiring about the wiring for this particular one, drawings sent to me have included the daisy-chained parallel wiring for the sockets, but no lead from the live wire... or the fuse left out altogether, or they've never heard of a volt/ammeter in one module (!) and advised to use analogue ones...
so I'm trying nothing without an expert.. 
I know it will work - it's just the wiring.
