@dtaylor89 - thank you for the detailed info, It has been super helpful! We are going to do a hardwired installation of the Chargepoint charger to an existing but unused 60a breaker. Am I correct in reading that if our plan is to hardwire, there is no difference in which model "plug" we get from Chargepoint? For hardwiring, the plug configuration is moot, correct?
Correct. But if you can get 14-50 it’s most common plug everyone is now putting in. So allows best flexibility moving forward.

I would not hardwire. I'd keep your flexibility and do the 14-50. Just my opinion. You will lose 10 amps of power capacity but it is really not that big of a loss in the bigger picture.

My state code requires GFCI breakers for all garage outlets, including NEMA 14-50 and NEMA 6-50 outlets. The electrician I will likely select to install our EVSE will ONLY hardwire. Here is their explanation:


Manufacturer’s Recommendations and Requirements
Most modern Electric Vehicle Supply Equipment (EVSE), or EV chargers, have built-in GFCI protection. When the unit is hardwired, there is no need for a GFCI breaker. If the unit is installed with a plug with a GFCI breaker, there can and will be faulty trips. The sensitivity of the breaker is higher than the EV charger, and the power draw from an EV charger can trip the breaker. Most, if not all, EV Charger manufacturers (Tesla, ChargePoint, Bosch, Nel-x’s Juicebox, and more) state that the EV Chargers should not be installed onto circuits with GFCI protection.

I’ve read through this thread but it’s not clear whether the EVSE supplied with the vehicle (I.e., the mobile charger) comes with a NEMA 15-50 plug for L2 240V charging. My impression from reading the owner manual is that the supplied EVSE only has a NEMA 5-15P plug for L1 120V charging. I’m familiar with the. EVSE for the Mustang Mach e, and it’ s supplied with 2 plug adapters — a 5-15P for L1 charging and a 14-50P for L2 charging. So there is no need for a third party EVSE like the ChargePoint unit. I tried to lookup whether Volvo parts offers a dedicated 14-50P EVSE, but I couldn’t find the XC40 P8 on the website. I’ve got the 14-50 receptacle on a 50A circuit installed already.

It comes with both. 14-50P is included.

I could have sworn I saw the charge cables available as accessories as well, which is presumably cheaper if you wanted to have a second that lives on your wall. Went looking for the link though and I can’t find it at all. I do suspect the dealer would sell you one, but as burak noted it comes with both outlets as detachable ends.

Some of you may already have a 240V outlet available but not in the 14-50P (four slot 50A) format that accepts the 4-prong plug with the Volvo cable. Mine was a 6-50P (three-slot 40A) outlet. There is no adaptor for this provided with the purchase, but there is an inexpensive adaptor for it that works fine. You need to set your charge speed in the car settings to 40A or below so as not to trip your circuit breaker, but the charge speed is good, just not quite the 48A the cable is rated for. Here's a link to the adaptor.

I knew I wasn’t crazy! Here’s the listing for alternate cables if anyone is wondering about it.
