[Lancaster] OT : electrical installation

[andy baxter]

Hi all,

This is way OT, but does anyone know about the regulations around 
electrical installations in the UK? A friend of mine has asked me to 
build them a brew temperature controller for their micro-brewery, and it 
would be good to know where I stand with regard to all this.

One specific question is are people allowed to install their own 
electrical sockets? I would like them to have an RCD socket in the the 
wall to protect the circuit. They only cost about 15 quid, and I could 
probably do it myself safely enough, but I'm not a qualified electrician 
and I would like to know if doing so is likely to cause trouble for me 
or them later on.

Also, are there any rules which would apply to the rest of the system? 
Roughly, I'm planning to use a microcontroller to operate an AC solid 
state switch module, which would control a convection heater in the 
insulated cabinet they are building. This is a prebuilt module with 
screw terminals, not separate parts, so I think it should be safe, but 
again I would like to know if there's any legal stuff I could fall foul of.

any help appreciated,
