Electrical Wiring Requirements:
- The National Electrical Code (NEC) does not require a garbage disposal to have GFCI protection.
- The vibration caused by the operation of a garbage disposal can cause electrical connections to separate. Check for any loose connections in the wire compartment box at the base of the disposal.
- Garbage disposals should be either hardwired or connected to an outlet through a grounded electrical outlet.
- A dedicated circuit is generally recommended, although a circuit that is shared with a dishwasher is sometimes appropriate. The disposal’s user or installation manual should be consulted.
