If using it as a non-maintained is there any need for the emergency switch?

I'm fitting a non-maintained emergency light tomorrow (first one). There's an L1 terminal and an L2 terminal in the light.The L1 terminal on the light needs a permanent live. Regarding the emergency light grid switch - Does the permanent live from L1 then go the switch and return to L2 via the...

Thanks guys :)

Can the Manrose Man50T fan be ceiling mounted? The description(s) i've found don't seem to say.

I'll break the news to him gently today! :)

A customer i've been to see today wants his consumer unit and meter moving from the basement to the ground floor, around 40ft away. Can the meter tails be run through the floor joists? Or do they have to be accessible / visible?

I was just curious how the smoke alarms would be protected when the main switch is an RCD i.e. an RCBO not be applicable.

Wowzers! I wasn't expecting there to be so much involved in measuring the extraction rate! :^O I'll be honest and say I didn't carry out any of the aforemnetioned tests when I installed the fan. The bathroom is less than 10m2 and I felt that with the fan being directly above the shower it...

When the main switch in a consumer unit is an RCD are the mains fed smoke alarms controlled by an MCB as opposed to an RCBO?

I installed a shower extractor fan with a built-in light a couple of weeks ago. The customer rang me yesterday to say he doesn't think it's being very effective. The fan is installed in the attic space above the bathroom and is about a meter away from the ceiling cut out with the external grille...

If the person has carried out their own electrical wiring will they then just sign the design and construction part? I don't think that is the case in this instance but it'd be good to know.

Is this an acceptable way of doing it or will this potentially open up a can of worms?

I had a call from someone earlier today asking me to test (and hopefully certify!) some electrical work they've recently had done in their house, obviously by an electrician who isn't registered to a competent persons scheme. I believe i'm right in saying I can't certify the work in this type...

Where's the best place to get a copy of BS5839, Part 1 and 6?

No, the place used to be a pub but it's being converted into a shop, with a flat on the floor above.

Hi Guys, Is there a certain number of fire alarm sensors required per floor or per area? I can't seem to find an answer in big red, the onsite guide or the guide to the building regs.

A customer asked me if he could have them activated independently in his house. I suggested to him that it would be better to have them inter-linked but I just thought i'd put the feelers out to see how I would go about it.

Hi guys, Just a couple of questions regarding mains-fed smoke alarms if anyone can help: (1) Do mains-fed smoke alarms have to be wired in series or can I feed 2 smoke alarms from the 1 smoke alarm, via 3C + E? (2) With smoke alarms being inter-linked if 1 activates they will all activate. In...

Thanks guys. I'd assumed it wouldn't be down to me to sort but I thought it best to ask. Andy, i'm with m4tty i.e. no idea what a drop test is!

Hi guys, just after a bit of advice on this one if possible: Went to a property yesterday evening. The customer has an electric oven and a gas hob. She wants the gas hob changing to electric (she's already purchased the hob). Regarding capping off the gas supply to the current hob - Is this...
