ELECTRICAL CODE CHANGES: WHAT DIYers NEED TO KNOW

The National Electrical Code is revised every three years, and the 2020 code includes the following revisions that may affect DIYers.

A. GFCI protection is required almost anywhere current is drawn outdoors, including receptacles and AC condensing units. The only exception is lighting outlets.

B. Outlets in bath and shower areas are not allowed within an imaginary 3 x 8-ft. zone around tubs and showers. C. All garbage disposals must have GFCI protection. Also, islands and peninsulas must have a GFCI receptacle every 9 sq. ft. An island of 15 sq. ft., for example, requires two outlets. D. One- and two-family dwelling units must have an emergency disconnect at a readily accessible outside location. E. To protect the ever-growing collection of sensitive electronics, all new construction and panel board replacements must include surge protection. F. All basement receptacles—in finished or unfinished basements—must have GFCI protection. Before, only 15- and 20-amp 125volt receptacles were required to have it.
