TT System

[mikep]

First time working on a TT system, had to put in a new rod on a house, Got 44.6 ohms on the EFLZ reading but what sort of PFC readings should you get, I got 6 amps, this normal or have I been dreaming.

Many Thanks all.

Mike.

Sounds ok to me. I=V/R

I = 230/44.6 =5.16A

Short Circuit PFC will be much higher though

44.6/230 if I am not mistaken.

i think it is for your pefc but your pscc should be a lot higher. not done tt but some one will correct me if wrong

 

[Andy™]

your PSCC PFC! is the highest of L to E or L to N. in TT and TNS, L-N will be higher, in TNCS, they will be the same

[Andy™]

its close enough!

Semantics.

Correct, but semantics.

To the best of my knowledge, NOBODY asks for both figures (or am I wrong?)

You record the highest; which on a TT is ALWAYS going to be PSCC.

Think you may be, Voltage divided by Resistance gives you Current.

As this is the first Rod I have put in I was not sure what to expect, best to run it past the boys.

Good call. Happily acceptable rod Well done on your first TT
