1 Use copper or aluminum conductors rated to a minimum of 75°C.
2 Conductors must be the same size and material when terminating more than one conductor under these terminals.
3Double lugging is allowed only when conductors are paralleled to increase ampacity for a single circuit.
CAUTION
Do not modify the factory
lug configuration.
