Evening all ,I’m sure I saw on here recently a WYLEX mcb compatibilty chart showing what breakers fit which bus bars/boards. I’ve had a search and can’t find it, dont suppose the OP could bung it up again.
many thanks.
My intention is/was to wire up 2 ovens, and a hob, using MCBs in a CU located in a cupboard adjacent to the oven positions. Each oven to have its own DP switch adjacent.
The ovens will be mounted in what was an old chimney space and I had intended putting the switches in the brickwork at the...
Hi, I am having weird behaviour from my flat's electrics which I think will need an electrician. The flat is empty whilst it is being redecorated and there is nothing plugged in.
With no load the RCD trips some days and will not reset but other times is fine. I have discovered that if I switch...
Does any know of any RCBOs which will fit alongside these breakers?
Kitchen upgrade and I’ve told them kitchen sockets need rewired alongside putting on rcd protection.
Also recommended the whole board to be changed which they only want anything doing that’s involving kitchen.
If anyone could help me that would be great. Wired a sub-main for an extension from an existing MK split load board in 16mm t+e. MK don't seem to make a 63a MCB for it 50 is the highest. Does anyone know which brand MCB (if there is one) suitable or will just fit in the CU? Wholesaler's...
I was wondering, are BS88 fuse boards still used on some new installations especially industrial and even commercial. And if so would that be ok with the regulations or not because its not retrospective. I know they are quite outdated and its hard to find a electrical wholesaler selling BS88...
Replacing a fan and some lights today at a job I'll be doing more work on, which has an "Emma" branded consumer unit.
Googling suggests that it's a rebranded Contactum board, and the housing looks identical to this image which supports that.
However, I also know that Contactum changed their...
Finished a refit of 7 x 200watt led lights to existing circuit.
The orignal circuit had 120 watts per light,so 140 watts x 7...say 1kw.
These are 1.4 kw,so not really loading the circuit.
There are other lights on the circuit,it’s a 10amp b type MCb.protecting it.
The lights are working, &...
hi all, I've been asked by a chippy mate to install an extractor in his workshop. Had a look at the spec and its 2.2kw so nothing major. Spec say to install on a 16a socket protected by a 30a d type mcb.
Ideally then a 2.5mm radial and 16a cform.
I understand the 30a d type is for start up and...
Hi all,
I am installing a Radial A2 circuit which by rule it should have an MCB of 32Amps, but when I reference the table 4D1A using reference method A or B, current are 26 and 32A respectivitly..
So the question is why we go for a 32A mcb and not 25A one?
Thanks
I changed 3 x 125A fuses for 3 x 125A D type MCBs (ABB). They held for a day and then two started tripping, we didn't have any spare 125A, so we fitted 100A C type and the issue has disappeared, can anyone shed any light on this for me please?
Hello all. A few years ago we had a new kitchen installed and as part of those works we had an electrician in to install a new feed to this kitchen and a full new consumer unit as well.
This is a metal CED branded unit with CED MCB's.
We have two showers, one upstairs and one downstairs.
The...
Hi all
Looked high and low for a Hager 50 amp 3871 for this board. Anyone know which newer 60898s would definately be compatible with these. I know photo is bad the existing ones are Type 2 M3's.
Thanks
So I was chatting with a friend tonight (also an electrician) and we were talking about disconnection times of C curve MCBs (as you do) and he was convinced he had a distant memory that 1mm t&e cable couldn't effectively be protected by a C curve 6amp mcb but couldn't give me a good reason. I've...
I've noticed at my grandparents house that all the MCB's in the consumer unit are all type C, every single one of them. Including the ring final circuits and lighting (there's no fluorescent lights in the house at all). The house isn't that old as well. Maybe about 16 years old. With me being a...
My Neff double oven is tripping the MCB on the mains.
This occurs when I switch on any function of the top oven. The model is U1744N (around 15 years old). The top oven has a double element at the top (grill and oven) with a second element under the casing at the bottom of the top oven. The...
Hello,
I am currently working on a project that previously utilises a charger for a battery system that is connected via single phase 240V AC mains. The existing charger has the 15A inlet running through a 1P 16A schneider MCB with the active line connected to the MCB (with earth and neutral...
Was called out to a car park where they had the lighting circuit tripping out. Fixed the issue by putting damaged cables in an IP rated box. However just realised that the electrician who came out before myself took out the RCBO and replaced it with an MCB in hope that it would stop tripping...
