As you are aware i live in cornwall,, and the supply company have a habit of supplying two houses with one cable. A 16mm concentric..
a couple of months ago i installed electric storage heating in two adjoining propeties, and i must be honest never gave the supply a thought.
I sent in the completion note so as to have the new economy 7 meter installed and left site.
Just heard to day that they wont install the new meters because the supply cable is not large enough,,, ha ha..
they want £2000.00 to install a second cable to one of the properties,, (overhead by the way,, no diging).
So the question is to my fellow sparks is, do you think i have a case in telling them to get stuffed and they should install this for free. and each individual dewling should have a 100amp supply, or there abouts?
Yeah, PaulC, I reckon you do have a case there. After all, it is thier Mains that are the problem here. Is feeding more than one house off of the same Mains cable a common occurrence?. And another thing is, they should have figured a certain amount of future load increase ito the equation when they specified the original cable sizing. I'd tell them "Tough!"
Yep even my house is connected to next door.. good job she doesnt fiddle the electric cause we would be well over loaded...
No seriously though,, down here it seems to be the norm..
not worked the loading out on a 16mm concentric, but i wouldnt have thought it was much more than 80amps buried in the ground or in free air,, even though the supply company put 100amp fuses in there cutouts.. That would give each house a 50amp loading.. Plus diversity..

This isn't a problem I've come across much in this area (rural east Norfolk). That said, my own house does share a single-phase branch from the nearest pole with the house next door, looped from the older-style individual overhead cables. But those cables appear to be 25 sq. mm. (or possibly the earlier 19/.052 size) and there's only one of us with electric heating loads (myself).
I suspect you may have a hard time getting the PoCo to foot the whole bill, but £2000 seems a bit steep for just running another overhead service drop.
Is the pole serving these two houses already run with 3-phase 4-wire, or is it just single-phase from a xfmr serving just these properties? If the latter, then maybe they're expecting a contribution to upgrade the xfmr.

Paul, Sorry, you have a poor case. It may seem unfair but the prospective additional load should have been notified to the supply company before the job was undertaken. It may be that a contrite approach will receive a more sympathetic outcome.
