Charging from a 30 amp L6-30R outlet

their NEMA 14-50 cable is labeled "40 amp" - once again the "draw" amount - not the breaker required
this seems to be an odd cable for 30 amp charging with 40 amp breakers - I"m betting it is used for their Hybrid products all of which max out at 7.2 kw - or 240 volts @ 30 amps - which would require a 40 amp breaker.
that's my analysis.

My 30 amp 14-50 cable came with a Porsche Universal Charger (9.6kw 40 amp) that I purchased used. It probably was supplied with a Porsche hybrid.

I’m not trying to be smug - but I think we all have a better idea what’s going on in this space now - I had no idea Porsche had a 30 amp supply cable with a NEMA 14-50 plug - it is very very likely a hybrid configuration meant for use with a 40 or 50 amp breaker - but will only supply 7.2 kW “raw” power
in my mind this all makes perfect sense.

your cable appears to be a 'rare' EVSE supply cable for use in North America on 40 amp circuits with NEMA 14-50 plug - which is building code for that type of 240V circuit…since there is no actual NEMA plug-type for a 40 amp circuit and the 30 is too small and the 50 is too big - but too big is also safe - so building code allows the NEMA 14-50 to be used for a 40 amp circuit.
learn something new every day - it's also why I didn't recognize the part number.
that cable is for a 40 amp circuit - porsche hybrids wich have a 32 amp on board charger (7.2 kW)

And the microchip from the cable still dictates how much current the charger will demand.

My 918 came with the the first generation Porsche charger (same size as the Taycan Connect charger), the cables, be it 14-50, 6-50, 14-30 or whatever, has no marking for amperage. I have all 3 at home.
My Panamera turbo S came with the 'hybrid' charger, the 14-50 cable is marked with 40A. My Audi e-Tron came with the same charger as the Panamera (thin casing as opposed to the thick casing as the 918 charger) and also have marked cables.
I was trial fitting the cables at home, the cables while looking similar, aren't interconnectable. The 'thin' charger cables can't be connected to the 'thick' charger, and the 918 charger cables can't be connected to either the thick or the thin ones. Even when the connectors looked similar enough. Porsche knows how to squeeze extra money from owners.

daveoporsche, oh wise one, please, oh please, just tell me what to buy. Break it down for me like you were writing "Charging for Dummies for Really Old People."
Ok, I buy a Taycan
My electrical panel ( located in the basement ) is full. No empty circuit breakers.
I have a 30 amp outlet that is being used by the dryer. The dryer is inside the house but shares the common wall with the garage.
Which cable or cables do I order with the Taycan?
What should I tell the electrician to quote me on?
As an aside, I'm not trying to save money. If there is an ideal charging scenario, hit me with it. Well maybe give me a less than ideal scenario too :-)

as for adaptors, a 110 plug and a 14-50 plug are delivered with the porsche EVSE

porsche seems to label their supply cables for the power "draw" _NOT_ the breaker size - so the cable is labeled "30 amps" - which means it would require a 40 amp breaker - which would also be ok to use with a NEMA 14-50 plug since there is _NO_ NEMA 40 amp plug…

In any event, back to the original question, a L6-30P->6-30R adapter like: https://www.parkworld.us/886450-p266.html would do. Combine with the Porsche 6-30 adapter.
