I've got some dimmers to look at. And source new trailing edge ones suitable for LED's. The thing being is they're for 2 chandeliers which have a LOT of lamps on. And as a rule of thumb using 1/10 of the wattage. I can't find anything capable of taking the load of about 30 lamps. Currently...

A little of a boo boo on my own part of not checking it was done completely done before leaving the job after leaving the lad to it...... but essentially the problem is am missing a cable to either a PIR on the landing or to the siren. As there's only one cable in the loft and I need 2...

In new build domestic properties building reg's require installation of extractor fans in wet areas and smoke alarms. In "renovations" and extensions in domestic properties, again building regs require smokes and extractors. Question, concerning re-wires and minor works. Obviously RCD/ mains...

To satisfy regs/building control..... I have some work to do on a house, a couple of additional lights and a consumers unit change. Whilst having a quick poke about etc I've come across that double insulated PVC singles have been used on the 2 way switching as the common. Question...

Went to look at a job this evening and they have an oil tank which will feed a new boiler going into the new extension. Now, the customer has had it mentioned that the tank should be bonded. But am I correct in thinking it should be the pipe where it enters the building (600mm etc) like the...

A customer has asked if I know of any standalone PIR's that are lux and dimmed. What I mean by this is that when the lux levels are low enough, the lights connected come on but only at say 50% brightness. Then when someone walks up the drive the PIR detects this and triggers the lights to...

A recent job has a combi boiler which is being swapped out for an ideal logic system boiler and tank. It's currently supplied by a 2.5t&e on a 6amp mcb. The boiler itself requires a local 3amp fuse. Which isn't s problem. But obviously now there's the tank to contend with. Can I swap out...

Hey guys. Anyone had any previous experience with a mitsubishi ecodan? Basically, we have all the details off the plumber, and have also called their pre-sales tech' line and still not got any solid answers. The unit it self has a running current of 10.3A, and specs for a 25A earth...

The last company i worked for would still run a 10mm earth to the incoming water main, even thought it was a plastic supply pipe and the internal plumbing installation was in plastic too. The only copper in the houses was always less than 1M long other than were the drops to the boiler and...

New build i'm wiring, the plumber doesn't seem to have much knowledge on what he's installing in regards as to wiring required. I've not really come into much UF heating installations, and any before the guy we used to use was really clued up on what he required to do his work. Or he used RF...

A switched FCU, taken from the ring main to isolate the the fire itself. The cable from the fused spur, does it have to go ceiling/floor, then either back up/down to the un-switched socket that'll be behind the fire? Or, is it ok to run the cable directly horizontally between the FCU and...

We've got an extension job at work, shell is up and first fix is about to start. The plans state interlinked smoke alarm's with battery back up to be installed if not inplace already.... (which they're not) The consumer unit is the old style wylex (5 way i think from memory), which looks...
