How To Wire a Dishwasher And Garbage Disposal Circuit?

Even while your dishwasher and trash disposal may share a 20-amp circuit, it’s not ideal. Dishwashers typically require a 15-amp dedicated circuit. The International Association of Certified Home Inspectors also suggests this.

Unless you have a 20 amp circuit that can support it, give the garbage disposal its own dedicated 15-amp circuit. However, a dishwasher is usually already equipped with a 15-amp circuit. A 15-amp circuit devoted to your trash disposal can be added instead of a 20-amp one.
