How should I prepare the electrical outlet for the HBL503 oven?

Contact your local utility company to verify that the present electric service to your home is adequate, as the size of wiring to the house and service switch may need to be increased to handle the electrical load. Most wiring codes require a separate circuit with a separate disconnect switch and fuses in the main entrance panel or separate switch and fuse box. Most local building regulations require that electrical wiring be done by licensed electricians according to regional electrical codes.
