Hi Steve,
There is no downside to replacing your broken J1772 connector with a
higher rated one that the Juicebox currently has (32A or 40A). All
amperage levels of the J1772 connectors and inlets are compatible
physically with each other, it just depends on the wiring of the cord or
max amps of the EVSE.
You also need to be aware that you'll need to crimp the wires onto the
L1, L2 and Gnd connectors, the pilot and prox can be soldered. The
crimps should be made with a pneumatic or air powered crimper, the hand
squeeze crimpers just don't apply enough force to actually make the wire
and connector homogeneous.
Best,

the connector on one of our EVSEs (a Juicebox) is broken, so I'm
looking for a replacement. Two questions:
1. I see there are connectors rated for 32, 40, or 50 amps. Is there
a downside to getting one with a higher rating than the charger?
2. Who makes a high-quality one and where can I buy it (not Amazon!)?
thanks,
Steve Gaarder
