Hi every one, I have got a bit of a problem i am hoping the pros that help in this section can help me.
basically i have just put a extractor fan in my kitchen (the house i live in) i only wanted it to come on when i turn my light on and turn off when my light turns off (did not want it to over run) so i used a 1.5 twin + cpc i used a mf junction box and connected the switch live to the live of the cable and the neutrals to the neutral of the cable and cpc to the cpcs then took it through the existing holes in the joists to the wall and chiseled a channel out of the wall down past where the fan is going to a isolator to isolate live and neutral then back up from there to the extractor and in to live and neutral,
well that is what i did any way then i did my dead tests r1 + r2 and insulation resistance all was fine so i turned the power back on and checked if it worked but it did not work so i checked if the isolator was on it was so then i checked if fan was live with my voltage indicator and it was so i tried all the lights on the circuit to check the neutral they all worked fine so i went back to the fan and did a Ze test and that worked fine with a good result 0.98 ohms which is well in the 6.18 ohms on table B6 page 119 in the onsite guide for a type b but the fan still does not work so i did not know what to do so (i know that i should not do this but i did) i turned it all off and took out the live and neutral and cpc of the fan and then go a spare light pendant and wired the cable into the pendant and put a bulb in it and then turned it back on and the light bulb worked it all lit up.
so is this a dodgy fan that i have baught.
o yeah i know that i have to down rate the fan to 3 amps as it says in the manufacturers data so what i did as i have a 16th edition board i think so no rcd i put a switched fused spur in with rcd incorporated in (from screw fix Product Code: 40097 ) and put a 3 amp fuse in it thiswas put above my consumer unit where the lighting cable comes out and connected into the cable there so the whole circuit was rcd protected and fused down to 3 amps this is more then enough as i only have 5 low energy light pendants
