  (x)  Electric Readiness for Alterations.

Electric range. Where branch circuits or receptacles are added or altered in a kitchen and the work requires a building permit, install electrical components in accordance with the California Electrical Code. The electrical components shall include either of the following:

A. A 125 volt, 20 amp electrical receptacle that is connected to the electric panel with a 120/240 volt 3 conductor branch circuit rated at 50 amps minimum, within three feet from the appliance and accessible to the appliance with no obstructions. Both ends of the unused conductor shall be labeled with the word “

B. A pathway for a future 240 volt 50 amp minimum branch circuit that shall consist of either conductors or raceway from the main electrical service panel. The main electric panel shall have space reserved to allow for the installation of a double pole circuit breaker for a future electric range installation. The reserved space shall be permanently marked as “For Future 240V use.” The raceway or conductors shall terminate at a junction box within three feet of the appliance. The blank cover shall be identified as “240V ready.”
1. Electric dryer. Where a branch circuit is added or altered within three feet of a gas or propane clothes dryer and the work requires a building permit, install electrical components in accordance with the California Electrical Code. The electrical components shall include either of the following:
A. A dedicated 125 volt, 20 amp electrical receptacle that is connected to the electric panel with a 120/240 volt 3 conductor branch circuit rated at 30 amps minimum, within three feet from the appliance and accessible to the appliance with no obstructions. Both ends of the unused conductor shall be labeled with the word “spare” and be electrically isolated. Space shall be reserved for a single pole circuit breaker in the electrical panel adjacent to the circuit breaker for the branch circuit and labeled with the words “Future Use;” or

B. A pathway for a future 240 volt 30 amp minimum branch circuit that shall consist of either conductors or raceway from the main electrical service panel.
