Seems a common thread......... Outside bulk head...separate PIR.......wired..... live to PIR, neutral to bulkhead, switched live back to bulkhead, ( pir marked L and L1 but with a N???)........ Bulkhead remains ON....constantly... tried all the normal stuff switched off and on etc etc etc...
Hi hope you can help, we have just carried out a survey of an office floor that we are due to fit out and the floor boxes and VAV units don't have separate Earth cables to them, even though there are numerous circuits the earth relies on 1 earth cable bolted onto the metal trunking by the...
Was working at a HMO house that's being renovated bit by bit. The work has been started by another spark and I've been drafted in to help. The other spark has wired sub mains, wired in 16mm 3c Swa with a seperate 10mm earth run with it. I've rewired the lights in one apartment and the sockets...

Hello there. I'm forever looking over these forums looking for advice, and typically I always find an answer, except it seems in this one instance - which is what brings me on my merry way to here today.
I was thinking of running a new supply to the garage. Problem is it has a water pipe (only...
Just a bit more from this job I've been going on about at the stables..
The chap has 10-15 meters of flex plugged in (just below Consumer unit) taking power to each individual flood. What sort of length of flex is acceptable? I'm going to be changing it all so they are on seperate MCB's in CU...
Hi,

If I'm running two core 25mm SWA as the submain with a 16mm (non-armoured) earth seperately then will the earth require its own mechanical protection?
Also as regards earthing the armour wire - will 6mm (from the tag to the earth block) be sufficient as it now counts as extraneous metalwork?
If a customer asks me to do a few jobs. E.g. Add some spots, add a socket and put a fan in a bathroom. As the only job notifiable to the labc would be the fan as its in a special location. Would you MW all jobs separately or all as one EIC and then let the building control deal with what's what?

Hi Guy & Gals,
So, I was reading a very interesting thread earlier where the OP was asking whether to use SWA or singles in trunking/containment for a supply to a sub main.
The responses the OP got were different to say the least!!!!!!!
Anyway, some were saying SWA and some were saying singles...
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...
if you have an existing installation where the earth bar in C.U is being used as the MET( main bonds/main earth) and you now split the tails via henly/switchfuse to install a submain. is there anything stopping you splitting the main earth in a seperate MET then feeding the existing C.U. and...
