Basically around a week ago my bathroom extractor fan started making an awful noise. I opened the cover and vacuumed, removed the fan head and tightened some screws that were loose, but nothing stopped the sound. I kinda felt like a monkey poking a keyboard with a stick so I called our landlord who said that despite the fan feeling really hot, making an awful noise they were going to leave it until it wasn't working.I brought it down again and sure enough, the motor spindle was loose with no way to tighten and felt incredibly hot. I went out with my wife, purchased a new fan from a building supplies contractor store that pulls 120m3 (the bathroom is tiny at 1.8x1.8x2.4m but I've no idea what the volume measurement means). I knew we wanted to keep electrics as-is because my experience with electrics is mostly how to barely avoid death. So I reasoned that I had to get a mains-powered pullcord design because I saw it had 3-wires in the current, coming out to a two-pin to the motor.Upon getting it home I noticed it had just two terminals to connect to, like the much cheaper consumer version I saw in a DIY store (I left because I considered it wouldn't be powerful enough... Probably an idiot for that). The last fan had two terminals direct to motor, but an adaptor board built in that took a standard live, neutral, earth UK layout (which I took a photo of so I could copy verbatim).Fast forward to today and I finally got round to taking down the old fan. I was pleasantly surprised that the hole for the vent that goes into our loft extractor box was the same size (must be a standard). Because the old mains adaptor was part of the old fan housing (sitting behind the fan, which wasn't possible with this fan) I took it out, and put it in a metal case surrounded by non-conductive foam insulation below. I am a little worried about that being dangerous AF as I've no idea if the foam is temperature safe, or at which temps it maintains it's non-conductive properties.I've wired it up exactly as it was before but I'm super paranoid around electricals. Should I call an electrician to verify my work? (Luckily my dad is a qualified electrician and I have several other family members that are sparkies I can trust). I don't mind paying them, but they don't take money so I don't like to ask them. Also they are likely to take the piss.I turned everything on and there don't seem to be any problems, but like I say I'm super paranoid about electrical works, even though I copied the original fan wiring as much as possible (cross-checking with the new fan's technical manual too) It was basically two wires and re-connecting wires in order). I suppose the worse that happens there is blow not suck according to my googling (then I'd turn off at fuse box and switch the order to the fan). I've put my hand against it and couldn't feel much air coming back. It's much quieter and seems faster than the last fan (which had an enormous motor).Advice? via /r/DIY http://ift.tt/2ik0oZl
