Long electrical wiring home runs
I’ve got a new construction home underway. My electrical meter is on the wall of my garage furthest from my house. My electrician ran the numbers both ways and said it was surprisingly cheaper to run all the homeruns from the house all the way back to the panel in the garage at the meter rather than run one or two big wires to a subpanel in the house and bring all the homeruns to it. What we did not discuss is how much electricity (i.e. money) am I loosing in lots of little wires spanning that additional 50′ or so rather than one big one. Frankly, this is now an intellectual exercise as the work has been done, but I’d still like to know if it is a meaningful amount. Thoughts?
Thanks for your time. I appreciate all the help I’ve received on this forum.
