PFC Help please

[nellyp]

I need a bit of help!

The scenario is:

Incoming supply to Henley block then out to two separate CU's.

TNC-S

Ze = 0.32
PEFC = 0.71 kA
PSCC = 0.71 kA
But when PSCC taken at CU 2 0.00kA ???

Kewtech KT60, three leads green to neutral bar

Any ideas???

TIA

Was the isolator in DB2 off?....in which case the neutral bar is isolated.

bonding still connected. parallel paths causing increased fault current

Has one of us had a blonde moment?....0.00ka is no fault current I'm thinking???

 

[telectrix]

hmmm. i read it as 20kA.

First thing I thought too.

Can see now how you thought that...I think the OP means 0.00ka...perhaps he can confirm.
