Never rely on low-voltage meters for IR values. When testing IR you are measuring leakage current Think of it like this: You have a bicycle tube that you need to test for leakage. The normal pressure is 30psi. You immerse the tube in water and pump it to 1psi. You dont see any bubbles so...

I don't agree but you can test it like this: The 2 wires that are in L2 at the dimmer... disconnect them and make sure they are not touching. Then check all the other lights in the house. If there are any other lights that no longer work this is a looped live and you don't have 2-way...

Not correct!! If they are using a neutral as an earth you will always get continuity due to the fact that the neutral and earth are connected together in the meter cabinet. [/b]

It was an old trick used years ago. When there was no earth available they connected the neutral to the metal parts. It is no longer acceptable. Basically, the earth wire connects to all exposed metal parts of an installation. The earth and neutral are joined together in the meter cabinet...

You will not be able to have normal 2-way switching unless you can run a new wire between both switches. It appears both switches are wired "in series". So both have to be on in order for the light to work. Turning either one off will prevent the light coming on regardless of what the other...

Run 2 wires from any existing socket to your new sockets in a ring formation. (I.e. 1 wire to each new socket and an interconnecting wire between them). Now you have 4 wires in the old socket ( 2 old, 2 new) For ease of explanation, we'll call the old cables A and B, and the new wires 1 and...

Its being used on an open vented system. I've taken an expansion pipe from beside the back boiler up over the header tank just for safety. The oil-fired end is open vented aswell. The blow-off valve is only for extra safety. Im well confident about the plumbing end, its just fitting the...

Yeah its an 18" solid fuel back boiler. I have oil fired central haeting aswell, the back boiler is only to supplement the oil haeting. Im a big fan of an open fire and will be having a fire most nights so i reckon i may aswell use the heat to save on oil. The back boiler is heating a dual...

Im about to fit a back boiler in my house, but having never done it before i would appreciate any tips that ye can give me. Its a new house so i have to fit the whole fireplace aswell. Im doing all the plumbing myself aswell, and have no problems with connecting the boiler, its just the...

WTF????? :?: Are you trying to say that these fuses were able to stop lightning that had jumped probably half a mile from the sky???. Due to the 1 inch(or so) gap left by the melted fuse-wire??? Sounds strange to me. Probably

Yeah, you're not supposed to do it but everyone does. It will probably be safer than him trying to solder or crimp the wires together. In my opinion those crimp connectors should be banned. People use vice grips and pliers to crimp them which give a terrible connection. Even using the proper...

Go with adams suggestion for a ceiling fan. Get the sparks to wire it into the light switch, with a permanent live to keep the fan running for a minute or 2 after the light is turned off again The fan you need is a 100mm timer model extractor fan. Available from all electric wholesalers. Dont...

Use a junction box. The crimps i think you are on about are not for mains voltage. Taping up choc blocks is against regs. You must use a j-box. 8)

6mm cable should be fine. It is not ideal to plaster over the old switch box if you have the connection there, but if it is unavoidable get a blanking plate put over it frist. 30A connectors should be fine but consider this: Get 45A or bigger connectors. Twist together the old/new wires...

For one, the j-box that you installed in the ceiling is a bad idea. You should not have terminations in inaccessable places. Two, Take two wires from the j-box and continue it along a ring to as many sockets as you need and then back to the j-box to complete the ring.

Sounds like a neutral nearby is joined to earth. Check all sockets in the kitchen. Possibly a neutral damaged when screwing the socket face on.

Better off to install a conduit or even 2 inch duct into the wall and run the wires through this in future. There are so many options depending upon your equipment/needs that it would be impossible to cover them all.

Usually when you quote a dangerous situation to a supply company they jump immediately to sort it (if only to cover their a*ses) I was looking to have a meter cabinet moved recently but the supply company wouldnt do any work until the cert was submitted. I was reluctant to submit the cert...

Any good wholesaler will sell you the interlock gear so that only one shower is on at one time. There are 2 types: 1. Priority- a pullcord switch in the main bathroom controls a changeover contactor, which energises shower in main bathroom and de-energises shower in other room. Main...

Yep, throw it out
