Minimum Recommended Wire Gauge
The minimum recommended wire gauge is:
•
C35 and C40 Models:
#8 AWG with a 75 °C (167 °F) insulation rating
•
C60 Models:
#6 AWG, with a 90 °C (194 °F) insulation rating
The terminals on the
C-Series
will accept up to #2 AWG
(33.6 mm
2
) copper or aluminum wire. However, UL
specifications only allow the use of up to #6 AWG
(13.3 mm
2
) maximum.
No crimp-on terminals or lugs are required.
Surge Protection
Since PV arrays are often mounted on an elevated structure
and thus are more susceptible to lightning strikes, protection
from lightning-induced power surges and other transient
power disturbances between the PV array and the
C-Series

determining your wire size. Due to printing anomalies, these
dimensions may not be to scale.
