It's a megger 1700 series. i have a 1500 series that I will try to confirm readings with

I will try a load across it later today when I return

Yeah but I am puzzled where from. Switch lines only, each line is run seperate from the other.

I am good John, how are you? I would guess it would be induced voltage, not sure where from though, as the circuit is run independent of any thing else. Live feed in shows no sign of induced voltage, when isolated. But switch lines do, never come across anything this high.

Recent rewire, 4 storey terrace house

Ideally they would be off, just to prevent marking and damage. But can easily be done with them on.

Tends to happen when tiles are removed from a dry lined wall. It's normal, should easily be repaired by a skilled plasterer.

Just been to test off a lighting circuit. r1+r2 fine at 1.01 ohms IR passes at +200 mohms Voltage at loop and switch line when closed is 240V Zs at the live loops OK Zs at switch lines OK But I am getting a voltage across the switch line when the switch is open. There are three lights on...

They both have rods attached and the cylinder allows both to enter the cylinder housing well. This occurs twice on the cylinder a set of two at the bottom then a set of two a third way up. This set uo allows for boost facility. Just never come across them being linked/paired like this. My...

I thought as much.

Could someone please explain why two elements would be linked across each other? Heating element (immersion) Backer BT 15/11 and BT11

You can purchase downlights that can be covered with thermal insulation. It is wise to give them ventilation, there are also insulation guards but if you are restricted with void space they will very likely not be usable. So I would go for a low profile fittings that can be covered in thermal...

That's a bugger My upstairs (where HUBB is) and front room (where TV is) are both radial circuits

That is great information Lucid, when you say ring main/ring final circuit, does that mean it does not work on radial circuit just a ring?

All interesting stuff and very much appreciated but TBH I would not know how to determine the measurements/readings you are discussing. Yes the Higher Mbps are at a hardwired to internet PC, the location/distance as the crow flys between the TV in question and the router is about 20 foot. The...

It is something I am considering, I recall when the original set up was installed a splitter was fitted for Digital TV (virgin media) and a hard wired to a router. Virgin media then removed this as the router was struggling to get a signal to my PC and the also upgraded the router.

Hi all, I have a TV that can only be used by WIFI. Have had something issues with buffering, disconnection and picture/sound synchronisation. I think this could be down to the WiFI speed. Was looking for something to improve this. The speed at router is 105Mbps download and upload 5.75Mbps...

I insert plastic conduit over the pipe, I assume they are going to be copper, but if you are using plasterboard just use amalgamating tape as a protection against corrosion where in contact with limestone walls and leave some expansion space.

A flame fault code is very vague and could be down to any one of a number of issues, the cheapest first fix would be the the ignition electrode but there is no guarantee that it is this. You will need GS registered engineer to do this, so is it worth calling one first for a visit, often best for...

With regards to water and gas. I am unaware of these services requiring above ground separation. There is a gas regulation for separations from electrical equipment though. OSG 7.4.3 'Separation of Gas Installation Pipework' (P76): "Gas installation pipes must be spaced a) at least 150mm from...
