NOTICE
• The circuit conductors shall have an ampacity not
less than the maximum total load to be controlled.
• For all connections, use min. 8 AWG wire for 40 A
loads or 10 AWG for 30 A loads, min. 90 o C (194
o F) rating.
• Over current protection shall have an interrupting
rating sufficient for the application control circuit

voltage and the total load current of the equipment
being controlled.
• A fuse or circuit breaker shall be connected in
series with each ungrounded conductor (and shall
be able to simultaneously open each conductor).
• Jumper wires are not included.
