Customer Question

I have a large piece of property the largest wire size the County will approve is 3/0 cooper. I need to go 1200 feet to supply a 200 amp service to a garage. I assume that parallels or transformers are my only options? Will step up and step down transformers be reasonable. I know that it is going to be an expense prospect either way. Getting the County to change their position is not an option. Any other suggestions?

Welcome to www.justanswer.com

Please give me just a little while to look at options, do some calculations, and get back with you.

Is aluminium an option?

Thank you

Customer: replied 3 months ago.
Aluminium is an option:Never used this service do didn't know where to put the detail. It took 5 weeks and $3000 to get a 200 Amp meter approved. It has 3/0 Copper as the service line and 3/0 out to a disconnect, that will handle double 3/0 lugs if I order them. I applied for a 400 amp residential service that was serviced by 500 Kcmil, but they made me rip it out of the ground after the utility company had already passed it.

OK, thank you.

This stringent requirement is a new one on me...never heard of anything like this.

I am working on it...will return

OK, thank you.

This stringent requirement is a new one on me...never heard of anything like this.

As an example, this would require 16 ea runs of 3/0 Triplex Aluminum or 11 ea runs of 3/0 Triplex Copper.

Obviously, your best solution would be to run utility primary voltage/high voltage overhead or underground, then set a transformer rated at utility high voltage (probably 7200 or 14,400 volts by 120/240)

I have not had any success finding estimates for overhead or underground primary installation. I will continue my search and let you know when I find the information.

Expert:  ProGrade replied 3 months ago.

A couple of options:

1l look for an electrical contractor that installs overhead/underground systems

2l ask the local utility company if they perform this type of work for individuals or if they have a subcontractor that does.

I haven't been able to find any reliable cost information for this type work.

I will be glad to pursue this further if you need more information, just let me know.

Thank you
