TT-no earth rod

[rich.250]

Are 100ma RCds still required? they have got a 16th ed split load board. half circuits on 30ma rcd, other half just MCBs.

also, for TT is the max Ze 200 ohms.

Table 41.5 sets out the maximum for different ratings of RCDs

at least your not going to hit a service pipe... lol!!!

It's the thought of hitting an MV cable that scares the hell out of me. I saw a bulldozer do it one time and it became something of a phobia after I saw the ensuing mayhem.

I got a rod stuck 200mm in one day. Thought I would test it.. :smilewinkgrin:

Are you being serious or did you mean 200cm? It would be a bit of a pointless exercise doing any testing on a rod that's only 20cm into the ground.

My mate's Dad was a HIAB op, I'll leave you to guess the rest but it wasn't pretty
