The on-line permit is available for properties in Sunnyvale with a residential zoning district. Zoning district information is available on-line by clicking on E-Zoning.
This permit will allow replacement of the existing electrical panel up to a maximum of 200 amps in the same location
Following is a listing of the general requirements for electrical panel replacements based on the 2013 California Electrical Code. This brochure is intended to provide general information, contact the Building Safety Division for any questions or additional information.
- General Requirements - The main electrical service shall be installed with rigid conduit. Electrical metallic tubing may be used where the service drop is attached to the building. The service entrance cable may be used, provided the approved fittings are used with the cable, such as a rain-tight service head or forming the cable goose-neck, taped or painted, and held securely in place by a fitting approved for the purpose. (Article 230)
The minimum size service conduit shall be 1-1/4”. The minimum size service entrance wire shall be rated 100 amperes minimum for single family dwellings. For single family homes, the service disconnect means shall have a rating of less than 100 amperes, 3-wire. A larger service may be required for new homes or additions to existing homes based on the actual load calculations. (CEC 230.79(c))
- Service Entrance Conductors (Wires) – Conductors that extend across a roof shall have a minimum vertical clearance of 3’ above the roof surface for roofs sloped 4:12 or more (18” clearance required when conductors enter through the roof overhang/eave). The service head shall be located so that the service drops, together with the open wires between the service head and service drop, will have a minimum clearance of 10’ vertically above ground and 3’ radius from doors and windows. (Article 230.24)
The neutral (grounded) conductor must be identified with white tape at both terminals. (Article 200.6)
After the panel is installed, one can safely buy equipment, which is not in danger from voltage drops. Any modern household appliances freely keep the voltage drops in the range of 160-240 Volts. There are manufacturers that provide their equipment with surge protection, such as smeg fridge Malaysia. The maximum protection of electrical appliances in our houses is provided by the combined use of voltage stabilizers and voltage monitoring relays. Refrigeration equipment has very sensitive controls, such as a Board and various sensors. Therefore, one should pay attention to the fridge, so as not to disrupt its full operation (Photo by Sidekix Media on Unsplash).
Service entrance conductors and cables shall be approved for a wet location and, when exposed to direct sunlight, shall be listed and marked as “sunlight resistant.” Service entrance conductors and conduit shall be sized according to the following table (CEC Table 310.5(b)(7) and chapter 9 table 1):
SERVICE ENTRANCE CONDUCTORS SIZE AND RATING Service or Feeder Rating Copper Conductors Aluminum or Copper-Clad Aluminum Minimum Conduit Size 100 Amps #4 AWG #2 AWG 1 ¼ inch 125 Amps #1/0 AWG 150 Amps #1 AWG #2/0 AWG 200 Amps #4/0 AWG 1 ½ inch
