What is the service entry size for a 200-amp electrical service?

#1-gauge copper
#2-gauge copper
#2/0-gauge copper
#3/0-gauge copper

The correct answer is: #2/0-gauge copper

The service entry size for a 200-amp electrical service is specifically #2/0-gauge copper. This gauge is determined based on the capacity needed to safely conduct 200 amps of electrical current while minimizing the risk of overheating or voltage drop. Using #2/0-gauge wire ensures that there is sufficient cross-sectional area to handle the electrical load, adhering to the National Electrical Code (NEC) standards for residential wiring. Copper is chosen due to its superior conductivity compared to other materials, making it ideal for residential service. This specific gauge is widely accepted within industry practices for installations involving 200-amp service. The other wire sizes mentioned are either too small or not appropriate for this level of service. While #1-gauge and #3/0-gauge wires can be used in different contexts, they do not match the specific requirements for a 200-amp residential service entry. Thus, #2/0-gauge copper effectively balances safety and performance for this level of electrical service.
