   Aug 12, 2017 · Technically it is not a "4 pole" as it does not take up 4 spaces in the panel. What you have there is a main breaker that is using two 200 Amp double pole with a single common trip. If you look closely at the two buss bars, you'll notice they split and give the illusion of 4 poles.

   What is a 4-pole circuit breaker?

   • A 4-pole circuit breaker offers similar functionality to a 3-pole breaker, with an additional pole for neutral line protection. While the neutral wire in an electrical system typically carries no current, there are circumstances where it can become live and pose a safety risk.

   What is a 3-pole breaker?

   • These systems consist of three different phases of AC electrical current, each of which is protected by one of the poles in the breaker. A 3-pole breaker can interrupt the circuit in all three phases simultaneously, providing comprehensive protection against overloads and short circuits.

   What does the number of Poles in a circuit breaker mean?

   • The number of poles in a circuit breaker refers to the number of circuits the device can protect. The poles represent individual switches within the breaker, each of which corresponds to a different wire or phase of electricity. Understanding 3-Pole Circuit Breakers A 3-pole circuit breaker is used primarily in three-

   Can a 4-pole breaker disconnect a neutral wire?

   • A 4-pole breaker can disconnect the neutral wire in such cases, preventing potential safety issues. Harmonic currents: Certain types of equipment, such as computers and energy-efficient lighting, can generate harmonic currents. These currents can cause the neutral wire to carry higher levels of current, posing a potential risk.
