admin, you on the lemonade????? ; \Normally they are TN-C-S, Admittedly. But it is not uknown for a TT to be too.
You can but you shouldn'tYeah I know ** In Matt Lucas voice ** Can I export PME?
550kA ? or 0.550kA ?ze is coming in at 0.45 pfc is 550 so it looks like tns it is. Couldnt get in touch with dno.
I would not think it is tns on overhead as earth comes off armour on tns. Maybe originnally it had two phases and one of the phases has been changed to earth. A few pics would help.righto old converted farm house in ormskirk. over head power cables with 3 cables.3 uninsulated cables come down to the house are then insulated then go down the side wall and into the property.2 cables go into a normal type fuse the other which is the earth goes to an earth conection bar.
