Being a tad lazy but have just looked at a 4 way board change.
Seems a bit silly to install a 3 + 4 way dual RCD board and I don't like the thought of a single RCD front end either. It made me wonder if there are any CU's on the market with a RCBO "bundle", say 2 x 32A, 1 x 16A and 1 x 6A...
Hi guys, new to this forum, started doing testing recently at work, got my 2391 a few years back and im just looking to brush up on a few things:
1: when doing an insulation resistance test and rcbo's are present do i have to disconnect both neutral and earth flying leads? and if so why?
2...
I have a problem to sort out - it is a TT system with a faulty 80A 10mA RCCB after the meter and before the consumer unit. The board is very old style MCBs with no RCDs present.
The customer called me up because until about 6 weeks ago the front garden lights were causing the RCCB to trip. I...
I'm looking for a single enclosure that will hold an RCBO. Every one that my local supplier have are only big enough for an MCB! Anybody suggest a make or site where would be best to get this?
my wholesaler's dont stock mem but said will get mem rcbo's in for me at £59 each
:shocked::shocked: no thanks i need 9 of them so it would cost a fortune.... anyway i know most rcbo's are around £30 just need to know a good source for MEM rcbo's or if you know of a different brand that will...
What exactly are the neutral leads for? and if a neutral to earth happened on a board with just RCBO'S in it, why doesnt the fault travel along that neutral and affect the other RCBO's?
Doing a rewire at the moment in an empty house. I am using RCBO's mostly so when i got 1 room complete i wired the 4mm radial into the RCBO so we could get the kettle going.
After several brews i went to disconnect it only to find i had wired it into a 6 Amp RCBO!
The trip never operated once...

Greetings.
There has been much talk of the unreliability of RCD's lately so I was wondering what are peoples thoughts on the most reliable.
Do you have a favourite brand?
What do you think is the worst brand?
I am hearing quite good things about MK brand but they are quite pricey.
Thanks.
Any one else come across the new 2 lead no trip feature trips some brands of rcbo's? so far i've found it trips wylex, crabtree and doorman smith. is their any work around or have i just got a dodgy meter?
Can anyone direct me to a citeable link which explains in detail how an RCBO works, and in particular what the functional earth connection is for please?
I was told today by a professional, highly experienced electrical engineering lecturer that it’s only for spike suppression, or bleeding off...
Hi all, great resource here...
Hopefully I'm posting this in the correct forum - I have a question regarding some items that I need for my CU.
I'm keen to get some RCD protection installed on the GE CU that I have in my live/work studio. Either through a 80a RCD as main switch or by...
Hi,
I was talking to another sparks that I know, and the conversation swayed onto leaving the wires from the RCBO's and not just cutting them off.
The conversation was cut short though and the reasons were not made to me to leave them as is.
And seeing another thread in the 'Electricians Arms'...
Hello All.
I have recently rewired a house, and fitted a TD-Line CU (main switch and all RCBO's).
All has been fine until now, 1x 6a RCBO for the kitchen and TV room lights has started making a sort of buzzing/humming noise. I haven't heard it myself but the client says that it isn't very...
Why do manufacturers give RCBO's curly neutral cables?
When you fit them into the board they look a right mess, especially when there are a lot of them. If they were given straight neutral cables you would be able to dress them all neatly down to the neutral bar just as you do with your...
is there anyone who can clarify the debate about single pole rcbos on a tt system???
i have a main 300mA s type DP rcd at origin and wanted to use rcbos on sub main cu's in other buildings instead of using a single 30mA device to protect a whole cu
as a whole board going down would be an issue...
