OK Struggling here, my calcs give a minimum voltage of 2 strings of 8 being 244v why is SB software stating its 198V??
What am I doing wrong
My thoughts were this was an OK substitute for the inverter of choice (PVI3600)
SMA software does not like this configeration?

When testing R1 + R2 on a three phase circuit, do you connect each phase in turn to earth and test at other end? Record the highest value? Similar to what you test Zs on 3 phase but without the connecting?
Cheers all.
Hi everyone,
Hope you are all enjoying the last Bank Holiday befor the Christmas rush starts !!!
Anyway, just a quick question to clarify if possible.
So, there are 5 flats converted in a big house.
3 phase supply, then into a meter for each flat, then out from each meter into an isolator for...
Does anyone have any experience in recording values of EFLI on circuits fed through a DB supplied via a UPS please? The meter shows the above scale arrow.
I understand that there will be no reference to the external earth due to the inverter inside the UPS but what will happen to the UPS...

Anyone have any advice on entering test results for multiple wires from the same MCB. It's a 32a MCB with a ring final and a further 3 wires stuffed into it, all of them radials. I'm not sure of the best way to express this on the cert without it looking a bit cluttered and probably all the more...

How many cables can you get into a 4 way wylex rewireable fuse board.
I have done a few CU swaps and the most i have ever come in one of these old boards is 12 cables a mixture of 1.5 and 2.5's,
But today......wait for it 21, yes 21 cables crammed into a 4 way wylex board, and 2 of them were...
If you are adding something on a circuit, ie another light, fan etc, when doing the r1+r2 do you get that from the part of circuit you have added or from the last in line point on that circuit??
Thanks.
Everything I have read so far about 'Insulation Resistance' testing only ever mentions 3 procedures:
Line - Neutral
Line - CPC
CPC - Neutral
But on the 'Minor Works' cert the first test it specifies, in the part pertaining to insulation resistance testing, is:
Line - Line
I've got the...
hi, guys, slight confusion here, installing a lighting circuit in a barn. job is likely to be used for assessment so it's got to be spot on. Coming from 10A MCB in 1.5mm to 2 gang switch, one switch for each of a bay of 4 x 6' twin fluorescents ( both runs in 1.5mm ). Done the cable calcs no...
Just called EON to find out the earthing arrangement of a commercial premises (not obvious whether TNS or TNCS). The lady didn't have a clue what I was talking about and said they could put a PME in if I wanted. I've not had to call before so am I being daft here? It is EON who should know this...
