I have a 200amps 120v panel, not 240. I need a single pole breaker of 100amps to supply a load. This type of breaker exists?? It’s a good practice use only one pole of a 240v 100amp breaker??
I need a transformer 480v/120v to supply a load of 20KVA @120v. I have problems sizing the capacity of the transformer if I only want to use 1phase. Should I use a 1phase or 3 phase transformer? What connection? Thanks in advanced.
