3 Phase 208 Leg

I was wondering if the only way to use the middle 208v leg for 110v was to use a double pole breaker on the 208v leg and either of the 2 other hot legs,then put 110v on each pole.
Any help is greatly appreciated,

Re: 3 Phase 208 Leg

It appears that you have a 120/208 3 phase service

Any single pole or circuit breaker will give you 110 volts
Any double pole or two circuits A/B, A/C, B/C will give you your 208 volts single phase
All 3 phases A/B/C will give you 208 volt 3 phase.

One should know when to back away or something is over your head. Thats why there are specialists.
