I am going to show the plumber the shower before i buy it so i imagine he will sort that.

Thanks for your reply rebuke. The shower i have seen is 10.5kw (i want a decent one as going to lose my bath to fit in new cubicle). The main switch is rated at 80A and only has 2 x 6a lighting circuits on. In your opinion will this shower be to much, don't want to buy it if electrician...

Evening, i am installing 3 x 2100w hand dryers on one circuit. Each dryer will be fused with a 13a FCU. As each unit is individually fused can i use 2.5mm on a 16a breaker. Or do i need to run the whole circuit in 4mm? Thanks

Thanks Coljack. Having the EM's on there own circuit will be easier, but if i do this and the power supply to the main lights fails the EM's will not come on. Is it relying on somebody switching them on? Or do the EL's have to lighted at all times for this setup?

Thanks for your quick and helpful replies. The setup will be that they are switchable lights. Firstly can anyone recommend which key/test switch to use? My main point of confusion is do the EM's have to be linked to the normal lighting circuit or do they have there own circuit breaker and...

Hi I have changed 2 transformers that feed 5 downlighters each on the same circuit. The first 5 work fine, but the second 5 are fine when turned on but then after about 30 mins start to go dull and gently flicker. After about 5 minutes of this they go back working fine for about another 30...

Thats fine. Yes i have double checked that all line and neutrals are correct and they are. It must be something to do with the switch (L1) live but can't seem to figure it out.

Continuity and Insulation Resistance were both fine. Run is fairly shot only about 35 meters in total so R1+R2 was low about 0.35 and all cable is new.

Hi, i have installed a PIR sensor for a hotel entrance, so that it rings a bell when someone triggers the sensor. I have wired as follows: from consumer unit to PIR - neutral, live and earth - then from PIR neutral and L1 to Bell Transformer - then from transformer to bell. When powered...
