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.

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...
