Not sure if anyone here can help at all, but I was wondering what is the legalities of making your own enclosures when it comes to wiring. I believe anything that's DC voltage (LED lights, etc) is fine. I'm not sure when it comes to buying a IR light fitting for the enclosure though. Seems you can buy the fittings very easy - but is it OK to install in an enclosure, provided it's not part of the house and that I don't have to do any actual wiring myself. (The unit already has a lead)? Same question if the wire has to be cut and passed through a hole? I know it's a straight out no-go if the unit is built into a house, but I can't seem to find any information about wiring for appliances such as this. Same question if there's a VIV that has a faulty wire - can I replace it myself, or must a qualified electrician do the work)? HAM radio operators seem to be able to build their own 240v gear without an electricians license, so my initial guess is that it's OK to wire appliances just not fixed fittings in houses, or wires through houses - but I can't find any firm information one way or the other. The only documented information all appears to be wiring for houses, and fixed appliances, and not for things like a VIV (or repairing a cord on a vacuum cleaner, etc). Talking around - it seems most people I've talked to believe it's OK to do - but no one has been able to point me to a qualified resource - it seems to be all assumption.
