do you mean that having more than one MCB installed alongside each other in a fuse board de rates it???

Just wondering, what would happen if you were to connect a 110v rated motor straight to a 230V supply. Would it 'blow'??

What do the following tems mean refer to: X10 Home Automation Thanks, declan

AT LAST! Somebody who I hope can explain these "design overload characteristics" of MCB's. BR & FWL spoke on such issues before but i could never understand. I think it was meant only for the ears (or should I say eyes) of high fluting electrical engineers. :) How did you calculate this where...

Is there some knack in opening these kind of cabinets. Even when I use the key and open both 'locks' the door still won't open??

Whats that on the tray just above the blue terminal block at the bottom. White thing??

thanks very much for the very helpful replys. Declan

Two issues i was wondering about: What does SELV stand for? Is it possible to get plastic surface box with a 20mm conduit knockout like the steel ones? If you were to drill a 20mm hole in a standard box, how exactly would you go about it? Thanks, Declan.

thanks very much adam you have answered my question. I presume a moulded case circuit breaker is similar to an mcb. perhaps fwl or br will know thanks again, declan

What do the following terms mean: MCCB RCCB thanks.

I have a question related to this which i would love to get a few opinions on. I know this might be bending the regs, i just want to get some peoples practical experience, maybe BR, Securespark and FWL if they get a chance. Q1. How much would a cable need to be overloaded by to pose a serious...

No foil lining, I will forward a photograph of some 5 core 2.5sq to breezers e-mail. I hope he doesn't mind :)

Thanks breezer, switched? is this the feed or the load?

i dont have a drum for it. It's not flex it's cable and has the rubbery stuff inside the outer insulation unlike flex. I have also seen it used for socket outlets in commersial premises. If that helps. I would imagine it is more expensive than standard T&E

This might sound like a silly question, but it's just something I wondered about. I have seen houses which have been 'first fixed', and where cables enter mounting boxes, ceiling roses etc., a little outer insulation is removed from the end of the cable (with the edge of a side cutters for...

Can somebody put a name on this kind of cable for me. I can be got in the standard sizes just like T&E however it is circular in section. When the outersheath is removed there is rubbery stuff that you can pull off with your fingers underneath. This cable is sometimes used outdoors. Thanks...

sounds messy to me. a better solution may be to fit a 20A MCB to the circuit instead. (If this is possible). Although connecting the cooker to the connection unit as it stands is not ideal, it wouldn’t be a huge issue.

did anybody hear of this company? they make cu's and MCB etc. Are they any good? DOEPKE

I have a few questions regarding 3 phase electricity. I would like to think i have a reasonable basis in domestic wiring but know very little about 3 phase. I am fully aware that putting into practice some of what i say here would be very dangerous. I am asking purely out of curiosity. 1. I...

I'm lost :) i was just wondering wheather accidently meggering a fridge which was accidently left plugged in will completly destroy it or what? What about neon indicators in FCU's etc?
