    (Another!) Main switch tripping...

    Called out to elderly couple's house today - no power. All 3 lighting circuit breakers are tripped and mainswitch is off. Quick check reveals PIR lightswitch faulty and 1 lamp failed. Replaced the PIR switch for standard 1G2W switch and reset everything, seems fine now. Question is, how did...

    Water heater (boiler) not heating water at night but it does during the day

    I have been having issues with my Boiler (water heater) - Horstmann Quartz e7. It has been working perfectly for 3.5 years (since I moved in to my place). Suddenly it stopped heating up water at night. It does not heat water at night even though it seems that the timer works at night. To make...

    bootlace ferrule crimper New Toy Today

    Another quiet day today so a bit of retail therapy was in order - this time on a bootlace ferrule crimper. Here he is with his first 6mm crimp. I'm hoping he'll settle into the toolbox in the next few days 'cause he seems a bit stroppy tonight. Maybe it's just me ...

    This area seems grey, can you are can't you? Part P.

    Hi guys, its seems everyone has differing opinions on this, including myself. From my research it seems pretty obvious that you can only carry out electrical work on somebodys house if you are part of a part p electrical scheme. From reading the forums and speaking to local electricians it...

    RISO seems low

    Hi, I have a 16 panel 4Kw solar panel system which is now 4 years old. The inverter is an Aurora Uno and is configured with two strings (SW and SE facing roof elevations).

    Bypassed Door Entry System

    I wonder if anyone can help me concerning an apparently compromised Videx audio intercom door entry system please? The system has a problem in that unauthorised people (e.g. leaflet droppers) without keys/codes/being 'buzzed' in are letting themselves into a block of flats by doing *something*...

    Pricing!!!

    This may come across as a very strange post but I need some general opinions on job pricing as this has baffled me! I have quoted for a job recently and a competitor has quoted around 60% of my price:speechless:. Their price in my opinion seems Ludacris! Installation is for an office conversion...

    Seems quiet tonight, so...

    Given a chessboard (8 x 8 square grid) and a piece which is only allowed to move one square upwards or rightwards (it cannot move diagonally, downwards or left). The piece starts in the bottom left corner of the board and you have to move it to the top right corner. There are clearly lots of...

    Button cells/batterys

    Seems they are not as harmless as they look.I realise they contain heavy metals like cadmium and mercury, but unless they leaked I surmised like many others they would if swallowed just pass through the system naturally.HOW WRONG I WAS!!! Seems the battery causes a chemical reaction which can...

    I've installed 4 lights, one with a built in PIR operated at the bottom of the garden which allows slave lights up to 1KW, at the top a separate PIR allowing 2kw also controlling the 4 lights. I've used a 4 core 1.5 SWA, using switched live to control all lights and i've let the common flow...

    Hmmm, seems high!

    First time I've had to do this but quoting for a small job for an elderly couple up the road. I was called up there a few days ago when half of their front garden pathway/spike lights stopped working. Traced the fault to a cut length of flex that was buried in the ground (bad I know). The...
