Edit: This is sounding more and more like a problem with either a neighbor's electrical or the utility's supply. See last entry. DON'T get in that hot tub again! The "very small" shock was due to high impedance between you and the current. Impedance is extremely luck-based. Someone getting out of the pool might splash water where it had not been before, ...

In the US, no the USB ports will not have power when the outlet is not powered. Most outlets in the US don't have power switches on them, so if you switch them off there is no way for power to be provided. In the UK, outlets often have power switches. In that case, your USB ports are usually powered while the outlet switches are off. This is because the ...

Is it supposed to be like that? There needs to be air circulation in unheated space to prevent condensation causing rot. It's freezing up there That is good. It means your loft insulation is working. I'm more concerned about animals entering the house. I found fixing wire-mesh externally to any small gaps at the top of the walls keeps unwelcome ...

Obviously, safety considerations like isolating that circuit are paramount, and note that even if that circuit's breaker is off, then the neutral touching earth can still trip the Earth Leakage Circuit Breaker... Find the socket / box that that wire goes to, disconnect it, then pull it out from the other end (which you need to find - either in the roof ...

I applaud your effort at frugality and environmentalism. The "throwaway" mindset peeves me to no end. Many folks change out fixtures just to change the look or size, and there are plenty of good units to be had. In fact, I'll soon be swapping out a perfectly serviceable round-bowl toilet for an elongated one just to better accommodate an add-on bidet. Some ...

Given the size and location of the wire, It looks like you hit the range feed which may draw upto 50 amps. Such high current applications require greater care in making connections such as splices. in general there are two safe approaches to repairing this damage. The easiest but most expensive (since you have conduit and assuming that it is continuous) is ...

I had an electrician to check out the problem and: I am in the UK and there is only live and neutral at the meter (earth and neutral are the same wire at that point) The Hot Tub water is directly conncted to Earth The mains electrics in my property all checked out fine, incoming supply fine. No faults with the Hob Tub RCD's tested and working He is ...

Insulated crimped connections are allowed in the UK, and considered maintenance-free so they can be concealed. A proper ratchet crimper is essential. The whole should then be wrapped in self-amalgamating tape.

Transformer, rectifier, regulator - aka, a USB power supply. There are, of course, the small switching supplies that plug in, as seen as phone, ipad, ipod (or any other USB device) chargers. I know that there are power outlets (ac) with built-in USB outlets available for the USA system - depending on the speed and conservatism of the UK electric regulators,...

That area is supposed to be open for venting the roof. However it should be covered with a material made of aluminum or vinyl with a type of screen to allow air to enter but keep small animals and rodents out. To get an idea of what I am talking about GOOGLE "soffit and fascia",and you will see typical installations. This roof area should be cold unless you ...

That looks like a Euro cylinder lock. You can remove it by undoing one bolt in the edge of the door then insert the key, turn an eighth of a turn and pull the cylinder out. Then measure the lengths in the diagram below. Or just measure externally. You should get an anti-snap lock which means you need to specify which of the measurements applies to the ...

Sometimes power supplies/transformers can hold voltage in capacitors to make it look like they are on for a short time after they are unplugged. Rather than checking with a tester, plug a phone (or anything that actually consumes power) into the charger and operate the switch to see if it is still on when the switch is off. It's not impossible for the USB ...

If you are going to spend good money to build an addition on your home why would you even consider someone else's thrown away junk. Spend money on "up to date" new and modern water saving toilets, sinks and faucets. If you supply them with old junk the plumbers will curse you for making them use this old stuff. If the plumbers have to clean the old stuff ...

You should not need to select a pair from the four live and neutral wires. In a ring main the incoming live is always connected to the outgoing live, the incoming neutral is always connected to the outgoing neutral. To add a second socket on the opposite wall you connect a new cable to all the existing cables - so you get three reds connected, three blacks ...

Rings Your quotation has a UK source. In the UK a "ring" refers to a ring-main also known as a ring-final circuit. This is the typical way UK houses have provided power to wall-sockets (outlets) since the 1950's. They are called rings because they are connected in the topological equivalent of a large circle. There are two routes back to the consumer unit (...

A DIY repair may be possible, though ugly, even if the wires are trapped so you cannot pull through any extra length or a replacement length of cable. Attach a 1-gang box to the wall in exactly the right place so you can cut the cable and bend the ends upwards into that box from below on opposite sides. Join Live to Live, Neutral to Neutral and Earth to ...

it's usually pretty easy to change the fittings: make sure electricity is off (turn off the breaker that powers the light) double check the electricity is off loosen the screws that hold it up on the ceiling and keep the wires attached. Remember which wire is connected to the ground (bare/green or yellow green striped wire), live (red, orange or blue wire) ...

No hinge amigo. Time to get new windows if you want these to open.

I'll be honest here: old toilets are terrible. I bought a house with original toilets from the mid 70s. These things were beasts that took a whopping 2 gallons per flush, and relied solely on gravity to do the work, which meant that it sometimes failed to get all the stuff down the drain (which meant another 2 gallon flush). That's pretty crappy (literally)....

I'm pretty darn sure the answer is "no" Non-metallic boxes, as well as oddly shaped/sized metal boxes, in the US are required to be permanently marked (labeled) with their "official" volume in cubic inches so that the correct box fill calculations can be run for them. This is Codified in NEC 314.16(A)(2): (2) Other Boxes. Boxes 1650 cm³ (100 in.&...

Yes flipping the switch will turn the power off. You will still want to double check at the outlet with a voltage tester. The objects to the left are fuses and are color coded to the amperage which you can also see embossed on the front (red is 30 amps; blue is 15 amps and I can't read the white one). If one blows then you will probably want to replace the ...

Yes - almost certainly. You need to get the wiring right (the wires should be colour coded in the usual way - if in doubt post pictures). The pins are in the same positions in both plugs. The 13A plug is fixed unlike the 5A. A fuse should be chosen to match the rating of the cord but you're unlikely to have that information. In that case just fit a 1A fuse ...

the "electric noises" is very likely arcing. If the other one works normally then the fix is to replace the entire outlet (the face plate is just a cosmetic cover).

These are a type of splice that in your case was a safe way to terminate the wire in the bottom photo. In my area they are referred by there brand name Wago. I only use these types of splices or connectors in fluorescent fixtures but they are or can be used as they are a listed connector. Some contractors use them because they are quick to install and take ...

That's not cool. Don't know your codes in the UK but that certainly is a fail in Canada and the US. Hanging a picture with a thumb tac can potentially puncture that. Actually no it's not to code, it can't be unless there is literally no code in place. (highly unlikely in the UK it might be code in a third world country) You need to have it fixed before you ...

Speaking from experience of doing just what you suggest... When doing up a house (UK) for my daughter we got a complete bathroom suite from Freecycle. All the porcelain and the enamelled bath were in good condition. The sink and bath waste fitting points took standard new wastes and traps, the sink just needed a suitable tap (single hole fitting). The ...

You can do work in people's houses, but you must certify your work to the current (Eighteenth) Edition of the Wiring Regulations. This is a legal requirement under part P of the Building Regulations in England. (Wales and Scotland have similar provisions.) The Wiring Regulations require either a Minor Works Certificate, or a Design Installation and Test ...

I have recently had issues with different electrical appliances ... Having the outlets very low down must put a strain on the leads where they enter the plug. Other than that any suspected problems with the electrical supply need to be discussed with the supplier. / light bulb ... Incandescent bulbs tend to fail when there is problems with the supply ...
