*Wires sizes larger than 2 AWG (35 mm
2
) must be terminated at a splicer
block located outside of the ProStar MPPT wiring box. Use 2 AWG
(35 mm
2
) or smaller wire to connect to the ProStar MPPT to the splicer
block.
Notes:
• The specified wire length is for a pair of conductors
from the solar or battery source to the controller (1-way
distance)
• For 24 volt systems, multiply the 1-way length in the table
by 2.
• Shaded cells in the table indicate that the current exceeds
the ampacity of the wire for a given ambient temperature
as defined in the following table:
Wire Ampacity** Key
Exceeds wire ampacity at 60°C ambient temperature
Exceeds wire ampacity at 50°C ambient temperature
Exceeds wire ampacity at 40°C ambient temperature
Exceeds wire ampacity at 30°C ambient temperature
**Ampacity for not more than three
current-carrying conductors in a raceway,
cable, or earth (buried) - Per 2011 NEC
