Charger overheating

[daveo4EV]

You can also change your breaker from 50 amps to 40 amps. The 40 amps will give you 32 amps continuous and you can set the Porsche charger at 100%. It should perform slightly better than the Porsche charger at 50%.

NO - 100% wrong - there is no magic - bad advice - dangerous advice - and the PMCC/PMC+ will _NOT_ magically "set themselves" to 32 amps if all you do is swap a breaker - there is no way for the PMC+/PMCC to "KNOW/DETECT" that you've swapped a breaker

OMG such bad bad bad assertion/advice - don't do it.

@mhockett This is not correct. You can’t swap a 50A breaker to a 40A breaker and run the PMC+ or PMCC at 100% on a 14-50 supply adapter - it will trip the breaker. Breakers do not regulate current in any way other than by breaking at their amperage rating.

+1 for @satchurator - I agree 100% with this post.

I agree with @daveo4EV - the post suggesting down-rating the breaker is bad advice that will (at best) lead to a breaker that pops every time you charge, or (at worst) a fire or other electrical fault.

The supply from the breaker is a dumb supply, it's up to the EVSE to know what it can safely pull which is currently enforced by the plug pigtail.

As a side note, the Porsche PMC+ sucks anyway, get yourself a Chargepoint Flex, Wallbox Pulsar Plus, Juicebox, literally anything else.
