You may be confusing the terms and parts; the whole "box" is usually called a consumer unit (CU) and the RCD is that special switch at the right of the CU which will trip if it detects electricity going where it shouldn't. There is no reason to suspect that there is anything wrong with the CU or...

Set the timer for, say, 7pm to 8pm when you are at home to find out if it's working.

You need to send it back. The size and material of the wires has been designed to give a useful and safe temperature. The resistance of the seat is fixed by the wires in the seat. The higher the voltage the greater the current through the seat and the higher the temperature of the wires. A...

Don't know if it helps, but I put a similar (not easy switch) in a redecorated bedroom about 4 years ago. The receiver is in the old switch and creates what is a effectively a two way circuit. Works very well.

If the tablet crashes and needs a hard reset - how will you do it?

Suspect reason for sealed meter and 'tiny tails' is that the latter are not properly connected, simply jammed into the sides of the terminals, which can only be done with a small wire (and often with the aid of a toothpick/wallplug etc).

Bathroom extractor link sounds most sensible with an RCBO in the CU to protect the whole circuit. There should be an isolator for the fan, so maybe that could be used as a JB.

How are they powered? Many have a wall wart or transformer.

rjm2k's advice seems best, but if you can't then... When you say,"unplugged" a circuit, what did you do? Common on dehumidifiers to have a 2 or more speed fan and a humidistat. A machine with labels "cool" on the outside won't be a simple dehumidifier - these just expel warmed air. Is it a...

Most dehumidifiers use a float which pushes up against a simple spring switch. From your description it sounds as though you have a pipe from a dehumidifier to a jerrycan which is remote to the unit (yes?). It depends upon the opening into the jerry can whether you can you a similar principle...

This is a question. On the basis of my limited electrical knowledge and (?) logic, I would have thought that (given all other protection is good and appropriate, the earth wire is sound caravan to generator and there is a RCD on the generator) : With neither generator or caravan earthed it...

What is above the ceiling from which the pendant drops? Is it possible to fit a well ventilated box above the ceiling? Easy in a bungalow, but feasible if a good clearance between ceiling and floor if this is a g/f room. Into the box fit a CLS 40W lamp and thence to the pendant in series. The...

Not clear from original post whether desire is (a) to just have a dimmed light thus lower voltage gives longer lamp life or (b) whether desire is to be able to change the amount of dimming. Bernardgreen's lamps in series would be a noiseless answer if (a). The pendant/holder arrangement becomes...

Recent thread on LED and spots which gives some relevant advice and links.

Sounds like the two black neutrals should be joined together with a short wire from this joint to the neutral on the lamp. All reds go together. The sleeved red over black goes directly to the lamp, or to a connection with a short wire from the connection to the lamp. Originally this is how it...

The camera must have some sort of transformer. If it uses a wall wart, then a fused 13A socket with a 3A fuse would solve your problems; if a separate unit then a 5A socket designed for lighting circuits would be a cheap and easy answer.

Have a look at the thread about LEDs in bathrooms - the link to a suitable spot might answer your questions.

OK You shouldn't have done it, but, for safety, the important thing now is to leave it alone. Turn off at the main switch and put a bit of duct tape over the switch so it can't accidentally be turned on. If it has old fuses you could pull them out if you want. Let the suppliers sort out the...

No he said 22 inches. No dubious jokes please;-)

You can do it, but it is not a very neat solution as they stick out from the wall. The load you can put on a double socket is for practical purposes the similar to that for a single socket so you would not gain extra output, e.g. If you have a 3KW electrical fire in on outlet, you cannot put...
