Wire Size
DC cables must be sized to carry the maximum full load current and to not exceed the
system volt drop requirements. The following cable sizes are recommended. When
running wires, if they pass through panels or wall, ensure the wires are protected
from damage by sharp edges. The use of cable glands is recommended.
