Hello,
I'm looking for a few pointers on changing the J1772 cord on the Blink. I find myself needing a longer cord, so I'd like to use the Leviton A3435-PEV, a 25-foot 30 amp J1772 cord I saw recommended in the Open EVSE thread. Doing it myself will hopefully be quicker and slightly cheaper than going through Blink. So I opened up the Blink and after taking a look I have a few questions:
1) The Blink J1772 cord has three #10 conductors (L1, L2, G) and one #18 conductor, the blue proximity wire. The Leviton J1772 cord has the same three #10 conductors but two #18 conductors, one blue and one orange. I assume the blue #18 is the proximity wire and I should leave the orange wire unterminated. Is that correct? What is the orange wire, and why does Leviton bother to include it if it is not needed? This may have been answered in the Open EVSE thread, but I couldn't find it.
2) The blue proximity wire currently goes through a pin and sleeve connection before landing at a terminal block. Is this a strain disconnect to satisfy the deenergization requirements of NEC 625.19? What kind of connectors are these? I'd like to get some more rather than cut the connector off the Blink cord and splice it onto the new cord.
3) Lastly, I notice that the L1 and L2 conductors on the Blink J1772 cord have sleeves crimped on them and then terminate in set screw connectors on a 40 amp circuit breaker. I understand the sleeves are required because the conductors are finely stranded and standard set screw connectors are only rated for Class B stranding. I'm a bit new to crimping and just have an inexpensive ratcheting tool for insulated crimps (Tool Aid 18900). Do I need a different crimping tool for uninsulated crimps like these sleeves?
Thanks,
Wayne
