Well I'm sure he'll be pleased to learn that there probably isn't another fault, as I wasn't happy to declare the all-clear when I left it. Thanks guys. I'd be more worried about damage the the (very old) bricks the house is constructed from around the area of the condensate drain ;)

You want a grid switch with one dimmer module and one switch module. MK, Crabtree and many others manufacture them.

Hello chaps. Got called round to a friend's house today after complaining of knocking sounds coming from the boiler. I wasn't expecting to be able to do anything about it, but said I'd have a look anyway and see if it was anything simple. Before arriving I had assumed it would be down to...

You may have bled the radiators, but did you actually refill them via the filling loop?

I think you should count yourself lucky rather than complaining. As already mentioned, some pay £1000+ for such supply upgrades, and you've managed to get it FOC. The only thing that would be wrong is if you didn't agree to have your driveway dug up, in which case I would expect it to be...

Well, you've already had it running from a 32A MCB when you plugged your 14.7A motor into one of the (13A...) sockets in the garage, and the inrush didn't trip the MCB then. Probably not, although I would not suggest having any of your outbuildings share an RCD that also supplies one or more...

12 metres is a long run @ 12v with that kind of wattage. I'd be surprised if any tension wire you can purchase (that will still fit the lamp terminals) will be big enough.

I suppose she thinks that -15 is short and shirts weather, then? :lol:

To quote Mark's site: I don’t have hourly rates, just set service charges, so you know exactly what the bill comes to, before I get there (plus spares of course). Doesn't seem too confusing to me :P

Yup, deep backbox and brush plate behind the TV, and a proper connection plate wherever your source(s) are located.

I've only had to do this a couple of times and in my own home, but I run 25mm round conduit for the signal cables. It's a sensible enough size to be able to chase in, and will quite easily take a coax, cat5e and 2x HDMI. There's really very little need to use SCART connections any more with a...

I'm not a plumber or gas engineer but rather an electrical engineer, so should probably stay well out of this. However, surely any heating appliance, be it a gas boiler or electric immersion, will deliver its rated output power into the load regardless of efficiency. On that basis, a boiler of...

I don't really understand why you would need this cable - the 4-pin molex as found on 3.5" hard drives and the like already carries both 5v and 12v.

I'm not sure anyone is disputing that providing a safety earth connection is not the intention of PEBs - they are there with the intention of providing an equal earth potential at all points within the installation. However, an added side affect of the PEBs is that an earth is also provided to...

I've seen it mentioned many times before on this forum, but I'm 99% sure it's nothing to do with BS7671. It might have come from the OSG...?

Although rather futile on account of the service already being bonded at your meter (unless you're looking at a huge length of pipe with a significant electrical impedance), there is no doubt that this (and any) conductive pipework between your and your neighbour's property is an extraneous...

You're right, phone cable is unacceptable, it's only cat3 and will not support the data rates of a modern network. While running and terminating network cables is relatively easy once you've done it a few times, may I suggest that if you are charging a client for this work, you do a little...

There is an exception provided: So perhaps the manufacturer intends connection by a means other than plug and socket? What do the instructions say?

Personally, I would do as you propose and bond either side of the flow meter, then get on with your life. It certainly wont be any less safe than picking and bonding one side of the pipework alone. After all, you are permitted to work to a standard that you feel you can prove is above and beyond...

While you've probably got some power there, I think it might be better if you didn't go poking around inside the immersion heater while the power is on :shock: Put the covers back on!
