So, I've got couple of quotes to the tune of $4K+ for hpwc and ~$2K for 14-50. Main panel full, so new subpanel is a must; switch over two 240V curcuits to subpanel and add new curcuit to garage ~110 feet. The prices are biting. And wondering about future capacity for multiple cars. Do we have people here with electrical background, who can clarify what might be a cheaper or more efficient setup: - Are multiple 14-50 outlets w/ 110 feet of wire each from a far away subpanel a cheaper option than 100amp wire connected to hpwc? - If 100amp wire is run into garage, does it need there another subpanel, disconnect switch, fuse box etc. (Which is preferred/appropriate?) so the capacity can be split between multiple appliances? I'm not just talking multiple hpwcs, but maybe a backup 14-50 or other type of charger. - why do different wires in the basement seem to use separate set of holes in joists to go through?(considering multiple 14-50 circuits) Is there a code that says they can't run nearby? In new houses they use those "glued wood chips" joists that seem only 1/2 inch thick if not less instead of 2 inch solid wood in older houses. These look incredibly flimsy to me and with holes all over them I am getting worried about floor giving way and having to fly down into the basement some day. - wondering if due to high cost it would make sense for me to buy 3-3-3-5 SER cable and just fish it end to end myself, so an electrician can save time on this mundane task and maybe I can save like $1K on it? Electricians seem to be not very forthcoming with info, so I'm wondering about true cost and what I can do to optimize this...seems to me that if an electrician makes $500 in labor on this in addition to material costs that'd be fair, no? And I can't imagine that materials would run more than $1500, most of which is 100 amp wire. I may be severely mustaken, in which case I apologize, not much knowledge on this.
