This permit will enable replacement the the existing electric panel approximately a preferably of 200 amps in the same location.Note: some properties in snucongo.org have actually an underground electric power feeding from PG&E. If her property has an underground strength feed, verify through PG&E the they can carry out increased power for a bigger panel size.To determine if the proposed panel is sized accordingly for your demands OR if you desire to check out if the proposed dashboard is big enough because that an all-electric house, please finish an electrical panel sizing spreadsheet. An electric permit is compelled for replacement and upgrade of the main electrical company panel before installation that the brand-new panel. Adhering to is a listing the the general requirements for electrical panel replacements based on the 2019 California electric Code. This magazine is to plan to carry out general information, call the building Safety department for any kind of questions or extr information.General Requirements - The key electrical company shall be mounted with strictly conduit. Electric metallic tubing may be provided where the business drop is attached to the building. The company entrance cable might be used, listed the approved fittings are used with the cable, such as a rain-tight service head or creating the cable goose-neck, videotaped or painted, and held securely in location by a fitting approved for the purpose. (Article 230)The minimum size service conduit shall be 1-1/4”. The minimum size service entrance cable shall be rated 100 amperes minimum for solitary family dwellings. For single family homes, the company disconnect way shall have actually a rating of much less than 100 amperes, 3-wire. A larger company may be required for new homes or enhancements to existing homes based upon the actual fill calculations. (CEC 230.79(C))Service entrance Conductors (Wires) – Conductors the extend throughout a roof shall have actually a minimum upright clearance the 3’ over the roof surface ar for roofs sloped 4:12 or an ext (18” clearance forced when conductors enter through the roof overhang/eave). The business head candlestick be located so the the company drops, together with the open wires in between the service head and service drop, will have actually a minimum clearance of 10’ vertically above ground and 3’ radius native doors and also windows. (Article 230.24)The neutral (grounded) conductor have to be determined with white tape in ~ both terminals. (Article 200.6(B)(4))Service entrance conductors and also cables candlestick be approved for a wet ar and, when exposed to straight sunlight, candlestick be listed and marked as “sunlight resistant.” service entrance conductors and conduit candlestick be sized according to the following table (based top top CEC thing 9 table 1):
Service or Feeder RatingCopper ConductorsAluminum or Copper-CladAluminumMinimum ConduitSize
100 Amps#4 AWG#2 AWG1 ¼ inch
125 Amps#2 AWG#1/0 AWG1 ¼ inch
150 Amps#1 AWG#2/0 AWG1 ¼ inch
200 Amps#2/0 AWG#4/0 AWG1 ½ inch
The grounding conductors should be determined by white or grey tape at both end (200.6).Meter location - PG&E calls for the elevation of the meter to be 48” come 66” above the ground. PG&E prohibits new meters on exterior walls adjacent to bedrooms or bedroom closets. A minimum horizontal clearance that 36” from the gas meter and piping is required.

Working space - The clear working space in prior of the dashboard shall it is in 30” vast by 36” deep with a minimum headroom clearance that 6’-6” (Article 110.26)Grounding the Services - grounding shall consists a consistent grounding electrode conductor operation from the panel to a ground rod (grounding electrode) and also to the cold water pipe. Ground connection of the electrical company at the main water line must be within the an initial 5’ that water piping right into the building. The underground water service shall not be provided as the grounding electrode without supplemental electrode. For brand-new structures and enhancements to existing structures, a concrete encased soil electrode shall it is in installed. This chandelier consist that 20’ the ½” ceiling or zinc-coated rebar or bare copper cable in the section of the footing in call with earth. (CEC 250.52(A)(3)(1) and also 250.52(A)(3)(2))For existing structures, the ground connection electrode shall it is in nonferrous (copper), listed, and not be less than 5/8” in diameter. The electrode candlestick be set up such the at least 8’ of size is in contract through the soil. The upper finish of the electrode shall it is in flush through or listed below ground level unless the above-ground end and the ground connection electrode conductor attachment is protected against physical damage. (CEC 250.52 (A)(5), 250.64(B))The compelled grounding electrode conductor (from electrode to panel) dimension is noted in the complying with table:

Bonding - Bonding the the hot, cold, and also gas currently is required when the electric panel is replaced. Bonding of the hot, cold, and gas currently is compelled with water business replacements (if utilizing a less conductive product than is existing) and for every re-pipes. Bonding candlestick consist the a consistent bond jumper installed at the water heater in between the hot, cold, and gas lines. The bonding jumper shall it is in sized based on the adhering to table.

The electric Panel allow is NOT accessible on-line if you are: installing the new electrical panel in a various location. installing a new electrical panel larger than 200 amps. Installing added sub-panels with the brand-new electrical panel. Performing extr electrical work-related in conjunction v the brand-new electrical dashboard installation.
If any kind of of the above conditions apply, the allow shall it is in issued at the One-Stop allow Center, City Hall, 456 W Olive Avenue. Specific process information is available at the Building department web site.
