Thanks in advance to whomever takes the time to read and reply. And to preface - I did review similar threads and could not find consensus / an answer to my specific scenario.
We are purchasing a M3P and MY. We have a newly built home with 200A service and panel with generous room for additions. Several major appliances use gas. We were looking to install two gen 3 wall connectors, and while we don’t drive enough daily to necessitate full 48A going to each vehicle simultaneously (and frankly would rather power share), if possible, I’d like to know we could have that capability. There is existing 1 and 1/4 in. PVC conduit going to the garage (30’ away) carrying some small gauge wires for lighting, the garage door opener, and a few standard outlets. The service to the house is underground. There is not a subpanel in the garage.
I have consulted with several local electricians and have received quite different recommendations. One electrician said he strictly would not put in two HPWCs and only would put in one, saying it’s too much continuous power draw. I have been told that the existing conduit is insufficient to be utilized for running the needed wires (presumably eight #6 Cu wires. Code seems to imply that 11 #6 wires may fill 1.25 inch PVC?). 4 of 7 electricians indicated a new area would need to be trenched out, 3 said existing conduit would work. Then 3 of 7 electricians said I would ”need” a sub-panel, other 4 said no sub-panel. One electrician said I would “need” to increase from 200A service.
As one may glean, I was surprised to get such a variance of answers and recommendations. Could anyone lend insight, and/or how they may have had theirs done?
