Electrical panel Permit demands The on-line permit is easily accessible for properties in bsci-ch.org v a residential zoning district. Zoning district information is accessible on-line by clicking on E-Zoning.The grounding conductors need to be established by white or grey tape in ~ both ends (200.6).Meter location - PG&E calls for the elevation of the meter to it is in 48” to 66” over the ground. PG&E prohibits new meters on exterior walls nearby to bedrooms or bedroom closets. A minimum horizontal clearance that 36” indigenous the gas meter and also piping is required.
You are watching: 200 amp service ground wire size
This allow will enable replacement of the existing electrical panel up to a best of 200 amps in the very same location.Note: part properties in bsci-ch.org have actually an underground electrical power feed from PG&E. If your property has actually an underground power feed, verify v PG&E the they can carry out increased strength for a larger panel size.To identify if the proposed dashboard is sized appropriately for your needs OR if you desire to view if the proposed panel is huge enough because that an all-electric house, please finish an electrical panel sizing spreadsheet. An electrical permit is required for replacement and upgrade of the main electrical business panel before installation the the new panel. Following is a listing the the basic requirements for electrical panel replacements based upon the 2019 California electrical Code. This magazine is plan to provide general information, call the structure Safety department for any kind of questions or extr information.General Requirements - The main electrical company shall be mounted with strictly conduit. Electrical metallic tubing might be offered where the service drop is attached come the building. The organization entrance cable might be used, detailed the authorized fittings are used with the cable, such as a rain-tight organization head or developing the cable goose-neck, recorded 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 organization entrance cable shall it is in rated 100 amperes minimum for single family dwellings. For single family homes, the organization disconnect means shall have a rating of much less than 100 amperes, 3-wire. A larger organization may be compelled for brand-new homes or enhancements to currently homes based on the actual load calculations. (CEC 230.79(C))Service enntrance gate Conductors (Wires) – Conductors the extend across a roof shall have actually a minimum vertical clearance that 3’ over the roof surface for roofs sloped 4:12 or an ext (18” clearance required when conductors get in through the roof overhang/eave). The service head chandelier be located so the the business drops, along with the open up wires in between the service head and service drop, will have a minimum clearance the 10’ vertically over ground and 3’ radius indigenous doors and windows. (Article 230.24)The neutral (grounded) conductor should be figured out with white tape at both terminals. (Article 200.6(B)(4))Service entrance conductors and cables shall be approved for a wet ar and, once exposed to direct sunlight, shall be provided and marked as “sunlight resistant.” service entrance conductors and also conduit candlestick be sized according to the complying with table (based on CEC chapter 9 table 1):
|SERVICE enntrance gate CONDUCTORS SIZE and RATING|
|Service or Feeder Rating||Copper Conductors||Aluminum or Copper-CladAluminum||Minimum ConduitSize|
|100 Amps||#4 AWG||#2 AWG||1 ¼ inch|
|125 Amps||#2 AWG||#1/0 AWG||1 ¼ inch|
|150 Amps||#1 AWG||#2/0 AWG||1 ¼ inch|
|200 Amps||#2/0 AWG||#4/0 AWG||1 ½ inch|

Working space - The clear working space in front of the dashboard shall it is in 30” broad by 36” deep through a minimum headroom clearance that 6’-6” (Article 110.26)Grounding of Services - grounding shall covers a continuous grounding electrode conductor run from the dashboard to a ground pole (grounding electrode) and to the cold water pipe. Grounding of the electrical service at the key water line need to be within the very first 5’ that water piping into the building. The secret water company shall not be provided as the grounding electrode there is no supplemental electrode. For new structures and enhancements to present structures, a concrete encased floor electrode shall be installed. This chandelier consist the 20’ of ½” bare 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 currently structures, the grounding electrode shall it is in nonferrous (copper), listed, and not be much less than 5/8” in diameter. The electrode shall be installed such the at the very least 8’ of size is in contract with the soil. The upper finish of the electrode shall be flush v or below ground level uneven the above-ground end and the grounding electrode conductor attachment is protected against physical damage. (CEC 250.52 (A)(5), 250.64(B))The required grounding electrode conductor (from electrode to panel) size is noted in the following table:
Bonding - Bonding the the hot, cold, and also gas present is compelled when the electrical panel is replaced. Bonding the the hot, cold, and gas present is forced with water service replacements (if utilizing a much less conductive material than is existing) and also for all re-pipes. Bonding chandelier consist of a consistent bond jumper installed at the water heater between the hot, cold, and also gas lines. The bonding jumper shall be sized based on the following table. (CEC250.4(A)(4))

|125 Amps||#8 AWG||#6 AWG|
|150 Amps||#6 AWG||#4 AWG|
|200 Amps||#4 AWG||#2 AWG|
The electrical Panel permit is NOT available on-line if you are: installation the brand-new electrical panel in a different location. installation a new electrical panel bigger than 200 amps. Installing additional sub-panels with the brand-new electrical panel. Performing additional electrical occupational in conjunction through the new electrical dashboard installation.

InspectionsA minimum of two inspections are required, a utility release and also a final. The energy release inspection have to be scheduled when the new panel is installed and ready to it is in hooked up the PG&E supply. The structure inspector will provide a utility release kind which will must be noted to PG&E to have the supply hooked as much as the brand-new panel. A cable lath investigate is forced for stucco repairs. A final inspection must be scheduled after all of the job-related is complete.
|If any type of of the over conditions apply, the permit shall it is in issued in ~ the One-Stop permit Center, City Hall, 456 W Olive Avenue. Specific procedure information is easily accessible at the Building department web site.|
