Two separate switches, A and B separated by the red line. The wires for each transfer to the new switches to the same connections. Wires for A to the new dimmer. Wires for B to the new switch. The only minor difference is that C on the new is L1 on the old. Nothing else is changed, you do...

Junk products which are solutions looking for problems no one ever had. 100% of what is on that channel is paid for sponsored content, so none of it should be taken as being credible.

That organisation has zero influence in what commercial media providers decide to pay for, Sky has a contract to use the satellites until 2029. They won't be renewing it as large parts of their service have already moved to streaming and the rest will follow. The satellites are EOL in 2030...

That is one of the reasons it's not been called PAT since 2020.

Only for a few more years. Gone in 3.

No. The threaded rod goes through the same hole.

Insulation resistance testing for circuits is done with all loads disconnected, because if loads are connected, faulty results will be obtained. They tested with the microwave connected - therefore they got defective results. Probably due to filter capacitors or other components within the...

The report is wrong. How it got to be wrong is something only the wrongun that completed it will know. Lack of SELV could only be C2 if it was required and it wasn't there. Bathroom extractors can be SELV but do not have to be. The only required SELV items in a bathroom would be desperately...

The only possible cable is the mains lead between the plug and the appliance. Tests on many items of equipment can be inconclusive or just entirely wrong. Whoever did the test should have told you what the problem was. If they are unable to do so, then they are just another blundering...

No.

If they are charging using a granny lead, there is no way of knowing. However anyone with ain installed EVSE will know as all of them report this and other information via the app.

The requirements for circuits in a bathroom to have RCDs protection is separate from whether supplementary bonding is required or not. All circuits in or passing through a bathroom have required RCD protection since the 17th edition in 2008. Supplementary bonding can be omitted in certain...

They don't work. 100% useless for any application. I have seen them a few times. The first occasion much time and effort was wasted attempting to get them to fit and secure the box in any meaningful way. Since then every time they are found they go straight in the bin and some other method of...

That will not comply with BS7671.

4x4 galvanised steel box with glands appropriate for the two cables, joints made with uninsulated butt crimps and heatshrink over.

No instant electric shower will meet that requirement. The flow rate is limited by the energy input. Doesn't matter how much the shower costs or who makes it. That won't be happening with an instant electric shower either, and it's probably flow, not pressure. Not applicable. Heating a certain...

Probably more like 15% remaining, but that is still more than enough.

That will be using a 'granny lead' 3 pin plug affair, which for a van will add about 6 miles of range for every hour of charging, so 5 hours = 30 miles. For longer distances a 7Kw unit would be installed which will do about 20 miles per hour or 100 for 5 hours. You can charge for as long as...
