Been asked to connect submains up
Have a 7 way ryefield board to split with 60 amp fuses in,has red fuses fake ones in each unit and meter will be there too
Do we require a main switch fuse for each sub-main or is the 60 amp fuse okay in each.
Isolater will also be after the meter

Hello,
I’m about to take on a mains room for a block of flats and the DNO are giving us a supply of 259kva.
Now, would I need a 200amp TP-N isolator or a 400amp TP-N isolator from the main head to the ryefield board? I am also assuming I will require a CT chamber. This is my first project of...

Hi, we are installing 3 x 3 phase sub mains from a Ryefield Board in a new warehouse, can I connect the SWA’s feeding the sub mains directly to the Ryefield Board, or do I need to install isolators, then connect to the Ryefield Board. There is a cut out, meter and isolator before the Ryefield Board.
Hoping to install (if things get back to normalish) a Ryefield board on a job soon. Haven’t installed one before, according to the drawing from UKPN, the meters will be after the ryefield board - will the suppliers do their own tails into the ryefield board or will I have to supply that? Seems a...

I'm interested in learning more about ryefield boards as none of my training so far has covered them. Does anyone know the relevant bs/bs en standards and legislation that applies? I've noticed g87, esqcr, iec 61439 and bs7671 seem to apply.
I'd like to know about who has responsibility for...

Hi,
I am quoting the switchgear for a BNO install. I have only worked on MEM (Glasgow) isolators but was looking at the contactum TPN 200amp isolator as another option.
I need some advice, if I should stick with the MEM. I will be terminating 95mm in the isolator after the UKPN cutout.

Does anyone know where I can get the missing plain top cover plate for a 24 way Ryefield Board? (see photo)
