Just before lunch on Boxing Day and minus 3 degrees outside a 600 bed hospital. I'm there to supervise the pest control operation. All usual safeguards and warnings checked and posted, but didn't consider smoke alarms as he was treating the floor only. Operator starts work; 30 seconds later all...

Probably wrong forum. Could mods move to help OP?

Hey, That's neat. Can't you wire it into the lighting circuit?

Maybe a stupid question, but how do you turn it on and off? When you say plug top, do you mean a wall-wart? If so they can object to the heat and die early if covered in insulation under a flat roof.

Unless I misread the question, all s/he needs for this task is to identify the cable used as switched live. Slow job on ones own, better with two but completely safe. Power off. Bulbs in. Disconnect each cable in turn, returning it to its original connector as one progresses. Test for continuity...

Oh well, here's my thought to get shot down: It's a mis-translation/interpretation. The intended meaning is that the sockets cannot be used for IT networks where there is no connection to earth (all the other systems join E to N somewhere). A fault on, say, electrothermy equipment in an...

No problem using the bigger fan, but to remove 280 cubic metres you need to allow another 280 in to replace it. You also need to avoid air short-cutting to the fan from an inlet. The design and placing of the inlets is key.

Best leave to selling problems until the time comes - the purchaser may wish to remove the flues anyway. You should, however, fit a carbon monoxide detector. Whilst a few people die from CO and solid fuel fires, many more just feel unwell, have a headache, bad dreams (etc) and never make the...

Looks like a CH pipe

Have you checked the voltage at each connection point?

It would make sense to just accept that some technologies, whilst not intrinsically unsafe are very unforgiving of mistakes. Secrecy, laziness and misunderstandings have been sources of those mistakes in the nuclear industry. Nuclear power has a bad record in some areas mostly because early...

Apart from the lists provided which apply to all electrical work, there may be requirements for other purposes. Apartment can mean a number of things from a completely self contained flat with separate entrance to a what is by law a HMO. You would need to check with the LA to find out the status...

Yes, I was thinking of a link in the new thread e.g. under the subject title "Leak detecting & RCDs" there could be a line "# RCD nuisance tripping 24/7/99" so that readers could back track if useful. No, I haven't tried either.

spin off alert.. The security answer doesn't have to be true for the "prove who you are before we let you in" question. A number of computer websites suggest using a false answer to questions like "Wife's middle name" as it prevents hackers easily building up a picture of your on line profile...

Would it be possible to use # (hash tag) to show a link to the original thread and at the same time indicating that the posting was a spin off discussion?

Simple answer to the bath is no because you cannot bond a plastic item electrically as plastic will not conduct electricity. The need for bonding for other items in the bathroom, such as taps, shower plumbing etc (which may or may not involve the earth) needs working out according to actual...

Don't know much about windfarms or changes in pressures around them (beyond exploding bats), but, about 40 years ago the then water authority and waterways board monitored the effects of forestation and deforestation in mid Wales on micro-climate, micro-wind patterns and local rain fall. There...

I hope you can make it work. I get a lot of interest and information from the spin-offs, but have on occasion found out later that I missed a few good contributions because I'd got as far as the answer to the OP and then not followed the thread on later days.

Ah, so insulated platform. Many thanks.
