What is the minimum size copper service entrance conductor for 145 amp service?
A #1 copper conductor with an insulation rating of 90 degrees C is rated at 145 amps.
How much current will flow in service wire?
In a service drop conductor the only limiting factor is the first over current device down stream from the service.
What size service ground is needed for a 350 parallel service?
The required size of the service grounding conductor for a 350 amp parallel service will depend on the specific installation requirements and local codes. It is recommended to consult with a licensed electrician or engineer to determine the proper size based on factors such as the type of wiring used, the distance between the service entrance and the transformer, and the local ground conditions.
What is the maximum amps each phase conductor carries on 200 amp residential service?
Each phase conductor on a 200 amp residential service typically carries up to 200 amps of current, assuming the load is evenly distributed across all three phases. Each phase conductor should be able to handle the maximum current capacity of the service to ensure safety and proper functioning of the electrical system.
800 amp service using parallel sets of 500 cu what size grounding electrode conductor?
For an 800 amp service with parallel sets of 500 kcmil copper conductors, the grounding electrode conductor size should be based on the largest conductor in the parallel set. The grounding electrode conductor size should be sized based on Table 250.66 in the NEC, which recommends a minimum size of 3/0 AWG copper for 1/0 AWG or larger service-entrance conductors.
