Frequently Asked Questions
Can I install a 48A charger on a 40A breaker?
Yes, but you must configure the internal dip switches or app commissioning to cap output at 32A continuous to prevent tripping the breaker.
Is hardwiring safer than using a NEMA 14-50 plug?
Yes. Hardwiring eliminates plug receptacle contact points, which are the #1 failure mode for EV charging thermal meltdowns.
Which charger is better: DEWALT Level 2 Portable NACS 32A or ChargePoint Home Flex?
Both are top-rated Level 2 EV chargers, but the DEWALT Level 2 Portable NACS 32A ($349) and ChargePoint Home Flex ($549) differ in cable flexibility, smart app features, and thermal management on a 48A circuit.
