I'm considering having 3 phase installed

[jouleflow]

Hi

I currently have a 100A single phase supply ( forgive the pun ) & I am considering asking for 3 phases to be installed. I have some workshop equipment that I want to install which are 3 phase and total about 30kW.
My property is fed by 2 cables overground on 7 telegraph type poles. My neighbour has 3 phase to a pole outside his house directly from a transformer. From the pole at my neighbours I am the only other consumer & I use one of the phases. So there are only two of us supplied from the recently upgraded transformer. It looks like I need a further two phases from the neighbours pole ran alongside my existing feed & associated consumer unit.
My questions are:
Do I have to use Western Power for the quotation?
Are there any other companies who can do this work?
Does anyone have experience in this type of installation & a rough guide to a price?
Is there a " standard " domestic 3 phase supply, I seem to remember reading something like 3x60A was below a threshold.
Can I still use economy 7?

Thanks in advance

Greg.

Be aware that if the recently installed transformer to which you refer has been installed under a certain time period [ i think 5 yrs but not 100 % sure, could be 10] then you would be required to pay half the cost of the transformer upgrade, which WPD would then refund to the person who paid for the original upgrade. You would ideally need to make a few discreet enquires before jumping in with both feet.

Thanks for the info, I believe the original transformer was just too old & it's time had come to be naturally replaced. It only serves two properties & neither of us paid for it.
