sorry this may seem obvious. All of the shower manufacturers stipulate the main swith must be rated > 80Amps for connection of their showers in their instructions, so when you fit a seperate Shower C.U. due to the old board either being full or a wylex 3036 does this mean that the rating of the...

We have installed a PV system which has 3 inverters and is protected by a 300mA RCCB. It runs directly back to the main incomer. However there's another circuit which runs from the same point which is protected by a 100mA rcd which is tripping. The 100mA RCD feeds a distribution board which...

Hi Guys
A customer wants to replace a class 2 fitting with a class 1 the lighting circuit does not have a CPC, I want to run a seperate 1.5mm CPC but as its less than 4mm does it need mechanical protection? And is it acceptable to only run it to the fitting in question?
Your help with this...

some plonker ordered and installed the wrong swa cable (too many cores not enough csa) but honestly the csa issue is only due to voltage drop. 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...
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.

Odd one. Installed a system last Thursday. all tested. All good.
Went back to adjust panels and as soon as we reconnected the RCD tripped... and continued to (and stand-alone). Seemed to trip as we approached 2kw (of 3.8) but might have been coincidence.
Checked the IR for the cable run...

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.
