Wire Size and Temperature Rating
Cables connecting the PMEC to the batteries should be sufficiently sized to prevent unwanted voltage
drop. Vanner recommends the voltage drop should be no greater than 0.5 between the PMEC‟s +12/24
volt terminal and the battery +12/24 volt terminal. In most installations, the PMEC’s terminals should be
wired directly to the battery terminals (reference fault protection) to prevent voltage drop that could occur
in switch contacts, connections, and long wire runs. Since the PMEC can be operated in temperatures up
to 60ºC, use wire rated at least 90ºC. See the Wire and Fuse Size Chart below.
