Posted By Topic: Mains Change-over

Jan 04 2019 20:13

What's the protocol and procedure for an electrician around changing over-head consumers mains to underground?

To clarify, the electrician runs the new mains underground to the existing pole and then does the HV company install the plinth and make the final change-over and connections on that end, or how does that work?

Contact the power co to see where they want it. That’s where you run to.

Not the power co.

Contact the network company - they will instruct their approved contractor to move the connection and shift the pole fuses if necessary.

For the Aurora network, the electrician runs the buried cable to the boundary and the approved network contractor takes it on from there. The electrician to supply sufficient cable length for 9m up the pole

In auckland if the poles within a metre of the boundary then you can run up the pole otherwise you're up for 5k for a pit

Only 1m? What if the pole is next to the gutter, across the footpath - 1m+?
They won't run across the footpath and do a pole top connection?

As Owen said above. In Aurora area, you take the cable to the boundary and the contractor(s) take it across the footpath and up the pole.

I can't remember the exact cost - maybe $1000 or so - they need specific contractors to dig across the footpath, and re-seal the footpath. And then another contractor to run up the pole and do the connection.

DougP, nope in my experience everything over a metre and they will install a pit at the boundary at your cost and do the connection in there.

DougP & OwenK are near correct on the Aurora network.
The electrician provides enough cable from the boundary to reach the pole plus 9m to reach the pole top even if it is across the foot park and grass verg. NEVER allow cable to go direct to pole, ALWAYS work at right angles when outside the property. the cable is installed by the network contractor and connected free of charge in lieu of the network taking ownership of the cable from the boundary.
There is a catch, If the pole is more than 2m past the property boundary a pillar box is the installed on the boundary. Then costs start to come in. This system works really well.
All ways talk to the network owner and do there paperwork even if its only an enquiry. Most networks have a paperwork tracking system so they can trace who's acting on your behalf
NEVER make your own decisions when work with a Network,

What happens if the pole is on a shared drive-way which feeds multiple houses. Only one house is having it's mains put underground. Is that generally still a case of running to the pole +9m or will that usually incite a pit to be dug?

Also at one point the consumer's mains comes out from the ground and has to run on the side of a small concrete bridgeway in conduit still and then goes back underground until it gets to the pole. Are there any issues with this?

Appreciate the help team!

if pole is on private ground theres no issue with digging to pole. same applies , leave enough to reach pole top and aurora won't charge. get the pole condition checked it maybe a do not climb pole.(PoLe will have a red tag on it)
Now you have an issue of who owns ground between house to be changed and pole. You carnet put an underground cable in someone else's property without a legal easement.
If you haven't an easement then a network shouldn't allow you to be connected.
This is why its important to ask your network for their help.

Most important thing, as nalla said, is
They all have their own preferred practices, which are often enforceable under their contact with the consumer. All such requirements should be available in writing in a "network connections" document.
All factors can vary between networks, everything from whether it's allowed at all to how it's done and who does it; so advice relating to one network can't be assumed to apply anywhere else. Plus they can change without any notice; so ALWAYS get the latest document.
