Hi All..
I have a 16mm 3 core swa feed a 9way split board in shed, 30m from incomer .. from the split board I have run a 10mm 3 core swa to 2 way board for hot tub. This has a 63amp rcd in it.. the other end at the split board is also a 63amp rcd on its own of one side of the split board.. this...
Hi All,
Just wanted to see what peoples opinion is
is installing a 30ma Split load board compliant/ non compliant under the 18th Edition or you have to use RCBO's for each final circuit?
BS7671:2018, Page 155 regulation 531.3.5.2 is a note which says on TN systems which states " Exept where...
Hi All,
I've posted on here before about this, that time i was asking what people thought about phase converters as at that point i thought i could only get a single phase line at 100a for my new workshop.
Turns out that after the DNO visited the site i can get a Split Phase connection put in...
I'm looking to install some LED lighting strips to light some display shelving.
It will consist of one driver going to a controller which will then be split into 8 x 1m length strips.
I was wondering if anyone can give me an idea on how to split the power from the controller to each strip i.e...
At the origin, I have 25mm tails split to two fused switches. One 63a fuse protecting a 16mm (3 core SWA) submain to a DB (100a main switch RCBO board) at one side of the property and one 80a fuse protecting a 25mm (3 core SWA) submain to a DB (100a main switch RCBO board) at the other side of...
Hi all, working with a spark today, basically dodgy wiring in kitchen junction boxes everywhere, all ripped out, now all we’re doing is a new 6mm cooker feed and radial socket circuit, basically new 2.5mm radial circuit from CU to one side of kitchen where spark I’m with has decided to put a...
Just done an EICR on a domestic, the sub main running from origin to cu is 25mm split con. Hard to know if its more than 50mm deep in walls etc without intrusive investigation. So could run with FI, but obv that doesn't deliver a satisfactory report.
Bit of a tricky one as it would have complied...
Hi gents I m looking for info comments advice that will help me look knowledgeable to my boss (money man) northen power grid. & mep consultant .
I have been given a project to split 26 student clusters (6 bed) into 54 x 2 bed flats. current supply and metering to each student cluster is as per...
Hi all.
How would you split MCBs where there are two ring final circuits (so better separate them). There is one electrical shower (will be on 40A).
Any ideas?
TNS system.
Hello all. I´m installing a new multi split Air Conditioning (Inverter Type) in my dwelling and I have to purchase all of the electrical parts needed for the installer. I am currently running a 63a Type-A RCCB and I was told by the electrician that I could use the Type-A with a 16a Type-C MCB...
Hi all.
Been doing a bit of work on a pub out in the sticks with a 460V split phase Supply. When tried to test phase - phase PSCC my tester didn't play along. I was going to use the double p - n rule of thumb but then I got thinking, does this still apply to a 460v supply?
I'm no expert on split concentric (assuming that's what this is)......But an earth clamp doesn't seem the best solution to this (also as the earth cores appear to be insulated!
This is for an eicr on a sub main but I'll have to do the remedial work at some stage.
Any advice on how to...
Hi Guys.
I'm in a tight spot and require a high integrity split load 22way (28modules total ) but NOT a stacked board but in a single row. I've seen one made by Proteus/M2 but Id rather not use CEF. Has anyone else come across one?
Many Thanks in advance
Got an issue at home, today I got home and found one of the RCD's had tripped on my split load Wylex DB.
I tried to reset but it wasn't having it. Switched all MCB's off on the RCD (Call it number 1) that had tripped then reset. All was ok, switched each MCB on and stayed in.
Put the kettle on...
Hi there, im looking some general advice related to this eicr.
im a bit lossed here, so would it be 2 eicr?
or do i just splice two sheets together with the relevant information?
on a seperate not i also noticed today when i had a wee look that his main water bond cannot be verified, is this a...
So Ze=0.02 and R1+R2 = 0.73 on a first floor ring main.
Nearest submain is about 35m away, so that Ze's plausible, and even a slightly indirect route makes Ze=0.03 realistic. So MCBs are going to need changing to Type Cs.
Unfortunately for that first floor ring R1+R2 of 0.73 is too high for a...
I currently have 4 double sockets on a 20amp Radial, I am looking to get a small air con unit (2.5kw I think) to cool a 5m by 3m space. Bearing in mind the only things plugged into the sockets are 2 PC and 2 Monitors at most, do you think a 20amp feed is enough?
It is a right pain to try and run...
