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?
Hi

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...
Hello All ,
I have finally completed a weekend project (it is a catering trailer therefore hooked up to different temporary supplies) and have come to testing and have wondered this , how can I get a Ze that will be relevant and how shall I record this fact ?I have done R1 + R2 for all...

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...
Hey guys,
Just a quick one.....
on the schedule of test results, which RCD reading is recorded; the highest 1x or the highest 5x? :rolleyes:
Thanks in advance.

this is confusing me.
now i know that the rcd times are ....
bsen 61008 and 9 should be less then 300ms
bs 4239 should be less than 200ms
rcd sokets at 200ms
but say i have tested a rcd at x1 180 degree = 35.2 and x5 at 180degree at = 12.6
if i remeber correctly is it
x1= max 50ms...

when doing a IR test, sometimes a reading starts climbing up and doesnt stop. Is there something on a circuit that causes this or is my tester playing up? if this is normal what reading do i record?:confused:
