This manual for use by qualified personnel only
Maximum One-way Distance and Wire Size
Refer to Table 4-4 or Table 4-5 and find the maximum current in the left column, and the
one-way distance from the PV array to the XW SCC (or the distance from the XW SCC to
the battery) on the same line, then read the wire size required at the top of the column.
For equivalent metric wire sizes, consult a local electrician or certified installer.

Important:
Local and national electrical codes must be followed for determining additional
installation requirements.
Larger wire sizes may be used to improve performance, but may not be installed directly into this
Charge Controller. Use a splicer block as previously described.
