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??
To be specific. I have an industrial 20kva ciberex UPS. The input voltage is 480 3phase and the output is just 120v 166 amps in only one circuit. For the alternate power I need a transformer to step down another supply source of 480v to 120v to support the load in an emergency. And the load is...
Thanks. But All of my load is 120v and the output of the transformer is 120/240. So if I use just one of the secondary windings what’s the maximum load I can use?? 50%?
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.
