wiring

Hi Folks, Looking for a bit of help here. We moved into our current house in 2018 and have always had a bit of an issue with the heating. The boiler is a Viessmann 200-W WB2B system boiler, and the central heating is split into the zones, each controlled by a thermostat. The boiler is plumbed...

Hi, We have a new cooker. Upon wiring it in the the RCD trips rated at 80A but the MCB doesn't rated at 40A. The cooker draws 8.5kW. it trips as soon as the double pole switch is made. The manual says use 2.5mm² which I am but my maths it should be bigger. Anyway, I feel like it is a fault with...

Good morning, I've had a look at a few threads featuring a horstmann H37XL however the wiring on the posts is slightly different in that our box has 2 lives, earths and neutrals. Our central heating is a 2 zone controlled by Drayton ZA5 aculators, oil fired and currently using the horstmann...

Hi was having a look at the wiring for my boiler (baxi duo tec a 24) to see if a nest thermostat would be suitable. My currant thermostat has a mind of it own. The wiring doesn't look right to me, just popping it all in a terminal strip together. Normally my dad would have a look (he was a...

I took delivery of a new dual fuel range cooker today to replace my old built-in single oven. However, I want to see if I can hook it up to the existing circuit, as given everything at the minute, I can't get (or rather don't want to get) an electrician out. Here's what I currently have...

Looking to get an outdoor light installed and I've already switched out the switch to a double switch but I'm not actually certain I can just connect the new light to the switch now... Basically the other switch is connected to a two way kitchen light and the other side is not connected to...

Hi All, First time I've ever posted on a forum. I was wondering if anyone can help me please. I've had a new heating system installed for a couple of years now but have an issue with our underfloor heating, connected to a Nest thermostat, probably the wrong thermostat to use but this is the...

I moved into a house where the smoke alarms were knackered (ground floor was both disconnected and expired, and the first floor was missing completely), so I bought two Aico Ei141RC alarms. The first floor fitting had the normal number of wires (L, N, E, IC) and took five minutes to fit. I then...

Hello, Was wondering if anyone could help me with a wiring issue I've been having for a few weeks now. I moved into my new home last year and just started getting round to changing the light fittings. Downstairs was easy, all blue and brown to blue and brown. Now I've started to do the...

Hi all Looking to wire 2 switches; one as a "master" and the other a push-to-break going off to a simple led light. How does the wiring look in the attachment? Not done it in a long long time! IMG_20200112_140653__01 by AdamEG posted 12 Jan 2020 at 2:15 PM
