so 13” (or 12”) is required for building code - cause they don’t want to much exposed wire…
so there is no function difference as I noted, but it’s a building-code/safety/requirements thing.
no reason - a supply cable is just wire with a plug on the end - short cables are cheaper and 13” seems about right for positioning the charger vs. the plug - also the longer the cord the more “hassle“ it is to manage, hide, prop up or simply keep it out the way - also for 240V wire there are...
right now on homedepot.com
50 ft of 10/2 wire (minimum gauge for 50 amps) - 3 conductor wire (2 hots + ground) is $126
50 ft of 10/3 wire (minimum gauge for 50 amps) - 4 conductor wire (2 hots, neutral, ground) is $173
so about a $1 foot
8 gauge is preferred for longer runs of 50 amps - and...
cost - purely cost - copper wire is expensive these days - and your electrician will pull either 3 wire 6/8 gauge wire (hot, hot, ground) or 4 wire 6/8 gauge wire (hot, hot, neutral, ground) - depending on time of day, supply chain issues, wholesale vs. retail, inventory, time, temperature, DJ...
no harm no foul - and I didn’t take it personally - this discussion (polite and informative in my opinion) is really discussing two searpate issues:
functional requirements
legal/building code requirements
functionally any EVSE _IN_ north american only required 3 conductors (2 hots + ground)...
RV parks - lots and lots of RV parks in north america - and motor-homes/trailers and RV’s have 240V/50 amp hookups - so they have power while camping at many many RV parks/campgrounds…
what type of plug will you find in an RV park?
you guessed it!!
NEMA 14-50
turns out the RV industry has...
Briefly…
Question: If the neutral is _NOT_ used or required by North American EVSE’s, then why are so many EVSE’s sold with a NEMA 14-50 plug type?
Answer: Compatibility/Ubiquity - _IF_ there is a 240V 50 amp plug-based circuit already installed the most common plug-type in North America will...
I never said building code does not require a neutral on NEMA 14-50 - I simply stated that any EVSE sold in North America does not use/require the Neutral for either a NEMA 14-50 or 14-30 plug type.
In fact inspection of the PMC+/PMCC supply cables demonstrate there is not even a neutral...
4 wire plugs types are un-necessary for North American EVSE’s - plug types like that that are supported by EVSE are provided for compatibility not requirements. NEMA 14-xx plug types are the “modern” versions of NEMA 6-xx plugs and therefore more likely to be found installed in modern homes...
at these price points the ClipperCreek HCS 100 stuff is in the mix and should be seriously considered - neighbor ordered his was told 6 week back order, and it arrived 5 days later…
not saying that will happen to you - but I think good companies under promise and overdeliver - and ClipperCreek...
only sadness IMHO is the 14.8 ft charging cable vs. industry standard 25 ft - for a $1600 charger I’d expect a 25 ft charging cable
I wonder if the 25ft charging cable part for the PMC+/PMCC is compatible with this charger?
5 hour charging times are nice but only required when car is nearly...
here is the install manual for the Porsche North American 19.2 kW EVSE…
breaker/output settings from 10 amp to 80 amp (charging capacity)
dip switches for 240V, 120V, 208V
only sadness is a 14.8 ft charging cable - a bit short for a $1600 charger
new charger from Porsche - $1600’ish - good feature set - adjustable install via dis-switches from 20-100 amp breaker setting
probably a good choice for an adjustable 100 amp EVSE in North America…

I’m looking...
I recomend either the Mustart EV chargers (32 amp or 40 amp) - or actually the Tesla Gen2 Mobile Chargers w/TeslaTap (32 amps) - from a cost point of view these two seem to offer the most bang for buck and are both high quality functional chargers with good NEMA adapter options at reasonable...
as noted @Jhenson29 you can get one via your porsche dealer - you can also just purchase a non-Porsche charger for not much more money than what porsche charges for extra supply cables.
if you own a TeslaTap/JDapter you can also just use your Tesla Mobile charger with the Taycan.
Tesla...
I agree @Jhenson29 and I didn’t think you were harshing on me because I’m above being criticized and all my post are 100% spot on and never wrong, biased or opinionated ;)
and in the adding insult to injury category for complexity a LOT of 32 amp EVSE’s have NEMA 14-50 or 6-50 plugs on them - confusing people into thinking they have a “50 amp charger” - but in reality it’s onlly a 32 amp charger
the reason the vendors use the 6-50 or 14-50 plug type is because...
actually it’s even worse than that
some EVSE vendors lable/size their products by breaker/circuit size
other EVSE vendors label/size their producct by charging capacity
so it gets even more confusing when trying to cross-shop EVSE from different vendors you have to be really really on your...
