So I was wondering your opinions on using multiple cores together as parallel conductors? I've looked at the regs and it looks okay but I may have missed...

    Lighting Dimmer Switch with seperate switch

    Can any one tell me of a manufacturer that still makes a lighting dimmer switch with a seperate on/off switch? To make up with grid components works out quite expensive. This is a request from a client who doesn't like the standard dimmer switch. Many thanks in advance for your replies.

    Dual MPP tracker inverter - two different panels?

    My colleague asked me earlier if it was possible to fit different panels to an inverter that had a two MPP trackers - for example a string of 10 Sharp 185s on one MPP tracker and another string of 7 Sharp 245s on another? I didn't know so I thought I'd ask on a forum where someone probably does.
