I don't see a power cord - does it need to be hard wired?

Many appliances do not come with a power cord. This leaves the option to the consumer to either hard wire to a terminal box, or purchase and install a power cord. You can purchase a three-prong power cord from any major hardware store. Power tool replacement cords work best, because they handle current well and have thick insulation to prevent chaffing. A good 15 to 20 amp cord is recommended. Whether you hard wire, or add a power cord that you can simply plug in, the wires as terminated as follows (U.S. Standard):

WHITE - NEUTRAL
BLACK - HOT (120VAC)
GREEN - Ground - terminate to ground lug

If you have any questions, please post back and let me know. I hope this helps you.
