[QUOTE="Mr Sworld, post: 14920, member: 184"] Hi. Welcome to the forum. :) Right, down to business. Any pre-made and PAT tested leads or fixtures are not classed as fixed wiring and therefore do not need to be tested to BS7671. As long as the PAT tests are up to date and they are suitable for the location they are in. I would make sure that you have an acceptable Ze reading if you are using a generator. A Zs reading at the end of the longest run will confirm any fuses/mcb's will trip in time but the presence of rcd's will overcome any problems. I would however fit a 300mA RCD at the source of the supply however to protect the wiring and to help with any supplies designated for sound and lighting companies. They DO NOT want 30mA rcd's on their supplies! Believe me! :^O The best test is polarity (to ensure nothing has been swapped over in the c/forms and test the rcd's to ensure they trip in time. Hope this helps, if you have any more questions I'll be happy to help. :D [/QUOTE]
