So so so much work being accomplished. Kudos to you guys and the utility crew supporting you. I worked for a utility company for 20 years (20 years ago) so you’re speaking familiar language to me on this part of your project. Most Pros don’t mind customers who ask a lot of questions if they’re smart, willing to work alongside and interested & appreciative. You two fit the bill. Carry on.
Thank you! We honestly can't say enough good things about our utility company. Throughout the process they've been incredibly helpful, communicative, co-operative and professional.
Interesting connection, so that shell is about 1/2 of a transformer vault: conduit with feed into it, then up to the transformer proper. Will it be filled only on the outside, or is it buried inside and out?
The fiberglass shell is basically a mount for the transformer which will sit on top and cover the big hole. The whole shell will be buried up to about 4" from the top, but the inside will be kept empty. The various conduits will poke in through the holes at the bottom of the fiberglass shell, emerging into the open space inside. The line crew will then make the connections up to the transformer on top as necessary.
Better to go by the electrical utility's requirements for the transformer. No mistakes, Once the transformer's in place than power can be run out fed through the dug up trench. All to electrical code. Nice tedious work that's time consuming but necessary.
Some of our rock is being taken away by the contractor and crushed, but it will become a much less regular fill - it'll be the same as the driveway fill material where there's a mix of larger rocks down to fines. This crushed rock is a much more standardized form required according to the specification - it's essentially to provide adequate drainage and a firm base which won't settle or heave.
