Terminal Torque Requirements

Once the wires have been installed, torque the terminals as
follows. Be careful not to overtighten.

20 inch-pounds for #14-10 AWG wire

25 inch-pounds for #8 AWG wire

35 inch-pounds for #6 AWG wire

Wire Size and Over-current Protection Requirements

The wiring, over-current protection devices (fuses and circuit
breakers), and installation methods used must conform to all
national and local electrical code requirements.

Wiring should be protected from physical damage with
conduit or a strain relief clamp. You should pull the
temperature sensor cable through the conduit first as the
connector may not fit if other wires have been pulled first.

Current Rating

Each model of the

C-Series controller

is rated for a maximum

continuous current of 35, 40 or 60 amps. Since PV outputs
can vary due to the array size or sunlight striking it, the safe
minimum wire size should be based on the maximum current
ratings.
