New supply from overhead pole

[dan35]

Hi all , if a new supply is being provided for a domestic new build from a overhead pole across the street would it mean that the earthing system would be a tt?
the cable is being ran down the pole then underground to the properties.
Have read on other posts that it may be tn-c-s.
Will be calling the supplier tomorrow , was just curious.
Many thanks. Dan

Has the DNO supplied a earth connection for you?

 

[dan35]

No , nothing has been installed yet will be in at the end of the month. Had a look at invoice and no earthing system has been specified

I suspect that'll it be PME.

Let us know what happens.

look at the other poles where its coming from, is there an earth dropped into the ground at each pole, hence the name multiple earth ...

Have a look at the poles the supply is to come from. For PME (CNE) every 2[SUP]nd[/SUP] or 3[SUP]rd[/SUP] pole will have a rod and down lead from the bottom neutral conductor.

Disregard the pole with the transformer on, the down lead will be for the transformer tank, this isn’t used for bonding the neutral due to the danger of MV faults affecting the LV system.

The assumption is it will be PME. Only in very rare cases is a new service non PME. As you say the O/H linesman will confirm.

Never assume anything.

I'm not sure if this is common across the country, but in my area the poles with electrodes connected have a label with the letters PME in reds writing on a white background attached to them. A quick wander down the street is enough to confirm it around here!

I went past a big factory with a tiger on the wall, and the place ain't full of big cats.
