[QUOTE="sparking mad, post: 416561, member: 27597"] what testing are you doing for a like for like replacement. (im newly qualified) e.g replacing over sink instant water heater 3kw. (bearing in mind my company do not want us testing and say its just maintenance, so they have not provided test equipment) but i think all work should be tested. i have recently replaced one, its in an old building fed from a DB that can not be fully isolated. i can isolate the water heater circuit but can not isolate full board to do dead tests. it is fed to a fused spur then flex to the water heater. i have changed the fused spur to an RCD fused spur. if i could isolate the whole board i would do the following tests, continuity, insulation, polaity, loop test(though i would just calculate this having done R1+R2) and RCD. since i can not, am i ok in to just to do Zs and RCD test and explain on the sheet why? (as long as previous paper work is to hand with Zs readings etc) [/QUOTE]
