Appliances - Hard-Wired
Major appliances that are hard-wired into the house.
Hard-wired means the electrical cable comes furnished with the appliance and is physically connected or wired into the household wiring. There is NO plug to plug in.
All built-in appliances (including Built-In Wall Ovens and Drop-In Ranges) have electrical leads attached to the appliance. In the case of electric built-in cooking appliances, there is a conduit coming from the appliance with the leads at the end. The leads can then be connected right into the household wiring. The wiring is copper. We do not use aluminum wiring; however, there is a light coating of tin that is silver in color covering the copper wire. This prevents the copper from oxidizing.
Warning - Installations with Aluminum House Wiring require attention:
- Improper connection of Aluminum house wiring to appliance copper leads can result in an electrical hazard or fire. Use only connectors designed for joining copper to aluminum and follow the manufacturer’s recommend procedure closely.
- Aluminum to Copper wiring connections must conform with the National Electrical code, local codes and industry-accepted wiring practices.
- If an anti-oxidant compound is added to the wiring connectors, the compound should be UL-Listed and suitable for the application materials, voltage and temperature.
- Connectors for joining Aluminum and Copper wiring may be larger in size than standard connectors. It is recommended to use a double-gang, or larger, electrical box to enclose the connectors joining Aluminum and Copper wiring.
Built-In Cooking & Ventilation Products:
All 240V electric built-in cooking appliances are hard-wired and include the following: 24", 27" and 30" single and double Wall Ovens, Electric and Induction Cooktops, Drop-In Ranges, Warming Drawers, and Vent Hoods. The power conduit with the leads at the end that is supplied on these appliances cannot be cut off; the installer is unable to add additional wire to the existing conduit cable.
Some 240V electric cooking appliances are also hard-wired, but do not come with a conduit. These include: Free-Standing Ranges, Slide-In Ranges and old "Hi/Lo" Ranges and 5-in-1 Advantium Ovens. Non-built-in 240V electric cooking products do NOT come with a cord, except 5-in-1 Advantium ovens.
Dishwashers & Disposers:
All Dishwashers built-in under the counter or the sink are designed for hard-wiring.
All Disposers can be hard-wired; corded models have the cord already attached to the hard-wire leads.
All other gas and electric appliances will use cords with plugs.
