The minimum size of the service entrance conductor varies based on factors such as the ampacity required for the service, the type of insulation, and local electrical codes. For instance, the National Electrical Code (NEC) in the U.S. typically requires a minimum of 1/0 AWG copper or 2/0 AWG aluminum wire for residential services of up to 200 amps. However, it's essential to consult local regulations and code requirements, as they may differ. Always consider the specific installation conditions, including temperature and length of the run, when determining conductor size.

If service is fed with service entrance conductors of 500 MCM THHN copper and fused at 400 amps What would be the minimum size of a copper grounding electrode conductor?
For a service rated at 400 amps using 500 MCM THHN copper conductors, the minimum size for a copper grounding electrode conductor (GEC) can be determined using the National Electrical Code (NEC) guidelines. According to NEC Table 250.66, for a service of 400 amps, the minimum size for a copper GEC is 4 AWG. However, if the GEC is connected to a ground rod, it must be a minimum of 6 AWG copper.
What size ground wire for a 400 amp panel in Quebec?
This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.

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.

A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.
Is number 3 copper ground conductor a common conductor size?
Answer for USA, Canada and countries running a 60 Hertz supply service.CEC states that a #3 bare copper conductor is a common grounding conductor size for a 200 amp service panel and it is the minium size for service raceway and service equipment of 400 amps.
What size service ground is needed for a 350 parallel service?
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
What is the minimum size neutral for three sets of parallel 500kcm copper conductors for a service?
