Hi,
I'm about to reroute cables and sockets/switches from the ceiling down to the socket height after insulating a wall.
I understand this will derate the cable, so what it the best way to do this please?
EDIT: Should be in DIY

Hi all, if I’m getting an insulation reading of 0.03 across N & L on a lighting circuit what would cause this? Neutral earth, live earth, are in the acceptable realms.
Hello,
I have a fairly big property and to get power to the house, there are several metal poles with the cables running along them.
I had multiple issues with lightning strikes and suspect that the lightning hits one of the poles and reaches the house through that route.
Additionally, the...
Hi,
I'm a little confused confused is someone can shine some light on the amendment 2 way of doing IR.
I know you have to do one 1st fix at 500V DC and then final one at 250V DC when all cables.
What I'm confused about is GN3 states:
"...sometimes these cables are terminated without further...
Slightly strange one this, replaced a few socket fronts in a dining room today, all wiring original but new plasterboard on a studded wall. Its a ring final circuit which does the rest of the house apart from the kitchen.
R1 and R2 all ok etc, loop test fine but doing the insulation resistance...
I want to check the insulation of the 3-phase 400VAC asynchronous squirrel cage motor.
Motor's stator windings are connected in delta.
I've read in some textbooks it is necessary to open motor's junction box and disconnect terminals and remove jumper bars (which are used to establish delta or...
Hi Everyone,
Sorry for all the questions.
With he help of a friend, I recently installed some insulation into my mother's loft. Whilst adding the insulation I noticed that a few cables (there are only light related cables in her loft) were tied together with electrical tape, so I spoke with...
Hey all,
Ive been in and out of a huge house rewiring as the renovate it for a year of so. Every is thing done and dusted except the downstairs shower. I ran a 10mm from the CU to a stud partition where the Isolator sits and then onto the shower. About 15-20m in total.
Ive gone back today and...
Could someone tell me if it is possible in fluke 1663/1664 to activate the option to carry out an insulation test without having the finger fixed on the test button? I am not referring to the differential test, which I know can be done by detecting voltage and not pressing the "start". I only...
During an insulation resistance test IR at an EICR I measured 0.0014 MegOhms from line to earth.
When I disconnected the neutral from the neutral bar it's 116 MegOhms lowest (on the outside bollards).
However measuring from disconnected neutrals to earth all read over 200 MegOhms.
So it...
I'm currently refurbishing a room and in the process adding some internal wall insulation.
The wall has been stripped and my electrician has completed first fix for new sockets and lighting.
The walls are solid brick and as I am installing insulated plasterboards, we agreed rather than...
Hi
My 4 bed 2 storey house was extended 2 years ago and completely re-wired, but I am having to upgrade the insulation and board out the loft myself.
In the loft the electricians clipped the new 1.0 mm wiring to the joists. There’s no ring, no JBs, it’s LED lighting only and all radial feed. No...
I need some help locating suitable led downlights to be installed in rigid celotex, they are being installed in a flat roof but there is 70mm of insulation behind the plasterboard. Does anyone know Of any lights that can do directly into the insulation.
Thanks
I have installed a circuit for an oven and carried out all of the relevant testing so far. Apart from a neon on the double pole isolation switch, there is no current using equipment connected to the circuit yet as the property is empty. In this situation, would one just make a note on the...
I was checking the IR on a socket circuit and found 0.4M between neutral/earth. The reading came from a garage door motor that was plugged in. once unplugged the IR was good. Does the circuit need to be cleared of all things plugged in when testing or does this constitute as a fault. I was...
So I have inherited a small job in a commercial clients own home. they want extra sockets in a bedroom they are renovating.
The walls are insulation backed plasterboard. I would guess around 25mm insulation on 12.5mm boards.
To add the extra sockets I was thinking of just chasing out the...
Just designing and taking into account the factors for insulation and can't decide on surrounded or on top of 100mm. What say you? Cables will be in metal banding inbetween the two layers as in pic. So to be clear it will be under the upper board in pic and above the lower board on top of the...
Hello guys,
I‘ll be building an insulated stud wall in front of a single skin brick wall (garage on the other side). There will be 2 couple mains ring sockets and media services, LAN cable etc. as I want to hang a TV on this wall, all running from the ceiling.
Will it be ok to clip the 2.5mm...
Hiya.
Does anyone recognise this wall insulation? I'm not sure I've come across it before. I'm pretty confident it's not asbestos but it is rather crumbly. Is it chasable do you know?
Was testing a 3 phase DB for storage heating. While testing I noticed I was getting continuity between 2 of the circuits, which were on separate phases. Each storage heater has its own 20A radial, and when doing an insulation resistance test between 2 of the circuits I get a reading of 0.00...
