The higher rated wires are only rated for 90C (194F), some rated for 75C (167F), so that seems a bit high.Outside temp is in the mid 80s with it being in the mid 90s in my garage so I thought I’d test charging our M3LR at the max 40a I can do. I started monitoring the temp of the outlet, plug, and cord going into the Grizzl-E charger and after about 30 minutes the highest temp I saw was on the side of the plug at 182 degrees F. The outlet was around 150 and cord was around 135. Nonetheless I dropped the amperage to 24 as I was not comfortable with those temps. The outlet is a Legrange rated at 75C. I really hate not being able to take advantage of the full 40a my charger can do. I submitted a ticket to Grizzl-E two days ago and have yet to hear anything.
I see in other threads for people with hot outlets in hot weather with the HPWC, for some people a breaker and outlet swap fixed things. Although for some it required a HPWC replacement (the ones still with 14-50 pigtails).
14-50 Wall connector over heating
Although hot weather does raise the temps proportionately (especially if there is poor to no ventilation on a hot day), a hot plug does usually point to a loose connection somewhere.
I don't really have a thermometer to test nor have I tried feeling the plug if it is hot, but I have charged when it is in the 80s outside (probably closer to 90s in garage where my 14-50 outlet is at) and my mobile connector at 32A does not have problems or throttling (knock on wood). My outlet however is right under my subpanel, and my main panel and service entrance is right on the opposite wall and a few feet away, so I have a relatively low resistance connection.
