1) Yes

2) Yes

3) Yes

4) Only on poles with defined bonding point (BUSCK) and yes still require gloves

5) Greenfields (New construction, no connection to any live network pole, no other consumer connections (no backfeeds))

Reasons we apply above:

Meets requirements of DeEnergised overhead lines guides protection from voltage differences – Section 8
we’ve chosen to insulate the worker to limit exposure to voltage differences

WEL – same as Electrix (Graeme.)

[Stephen Small]

1. No, 2. No, 3. No (U/G we prefer to isolate rather than bond wherever possible), 4. Yes, we cluster but No, 5. We have exceptions relating to distribution boxes feeding directly from unfused transformers, due to arc-flash risks.

However, almost all of our urban network is underground, and rural overhead is far easier to isolate. We also primarily work out of insulated buckets.

(I think we may be an outlier).

Same as Electrix and Wel. But a good conversation as we have constatnt complaints from Field Teams. Is anyone removing insulated gloves via the use of EPZ’s?

[Bill Doig]

We have no intention. Insulating gloves are your last line of defence and the wearing of Class 1’s on 11kV work (6.35kV to earth) is not onerous and no complaints from field staff

[Brian Ballantyne]

Thanks Craig- yes we are having same conversations around EPZ and cluster earthing removing the requirement for gloves.
