Discuss Does this henley block on the incoming tails of TT have a fuse in? in the UK Electrical Forum area at ElectriciansForums.net
The left one, yes.
Well that’s not confusing in any way…. Brown used for line and neutral and then disappears behind the board.
Just asking for a polarity mix up.

They are tagged at the meter and is all sealed.
OP
Thats what I thought. Likely to be a 60A dont you think. This in a town with a population of around 4000. I thought the DNO would have provided a PME supply but as far as I can see it is a TT. Measured the disconected main earth to electrode at 0.44 megohms. Seems to good to be a TT.
0.44 meg ohm 'seems good' ?
Plastic ones?

Been missing a lot of detail lately - in this instance six zeros.
OP
is for a TT...
0.44 Meg ohm is 440000 ohms.
I think there is some confusion over units here!
OP
You are of course correct. I Think i'm confusing myself. I cannot see any bonding conductors in the CU, yet when I get my wander lead out and test from the only earth conductor in there to the stopcock pipework and gas meter I get 0.00 Ω on each despite not being able to see any bonding conductors or earth clamps anywhere. Also when testing the ZE I was looking at my Megger testing a disconected main earth cable to earth electrode and got a reading of 0.44mΩ. I had in my head Ohms. This is of course megaohms... I haven't seen a TT system for a few years and I think I need to read up a bit. Thanks for your help..
You got a Ze of 0.44 meg ohm surely your tester does not give meg ohms on an earth fault loop test.

Obviously you need to check the means of earthing, Ze, and polarity no matter what for the EIC.
As above, if anything looks dodgy then EICR is a...
