First I would bell all the cables, find your faults and rectify if possible. If the customer wants a fuseboard change, You could probably get a metalclad board of your choice and put it into the place of that one and re-pot the pyro as necessary, the advantage being that modern units are much...
I would put them on a local lighting circuit, saves rcbo's, makes customer switch back on if fault etc etc. However neither way is really wrong as they do have backup batteries and will beep irritatingly until you put the power back on, as has been said.
fair enough mate, I value your opinion and everyone else's, that's what the site is for! :-)
I ran out Of smokes this morning so may have Been a bit sharp!
as an aside note, when installing new ccts. I would always IR them before connection, but I will stand by the global IR as a good method for...
it isnt a cop out it's a recommended method, it can only be done in installations where you can have everything off/ unplugged at once, which limits it to domestic, which is all this thread was ever about!
Even when you do it by the book you can't do it right according to this site lol
would agree with you on that one, global IR is pretty much confined to domestic, i cant think of many times on a commercial or industrial test that I've Been able to remove every load/ fly lead etc at once lol
on a domestic db, I would do a global IR test usually and only breakdown to individual circuits if problems are found, on a 3 phase db, I would test individual circuits, I was only referring to new all rcbo domestic db's with regards to grouping the flyleads anyhow :-)
Although I would have agreed with you until recently engineer, its not until I had to do a few EICR's when you have 10 RCBO's in a small placcy fuseboard and have to undo every cpc termination to do my IR tests and then redo them (some inevitably need re-terminating as well) that I thought any...
And your sure the tails don't come from another cutout in the downstairs flat?
Used to be common round our way to have 3 storeys blocks of flats with 3 phase cut-outs downstairs with L1 going ground floor L2 going to 1st floor (usually pyro) and L3 going to second floor (usually pyro).
Basically, you mean that rather then a concentric cable supplying the cutout, there was tails?
If this is the case, there will be a ryefield unit in the block of flats somewhere, if its a particularly scummy block it could be screwed into a riser, or locked under communal stairs etc. The...
As long as the cables are correctly sized for as you say they are I can see no problem with this setup, It would be more useful to be able to isolate each panelboard supply cable individually but Its not a regulation as far as I know.
I like the term 'bungled', makes me sound like a right bodging *** lol. I just think it makes sense when thinking of future EICR's on properites although it may sound a bit rough
