One and half breaker system is an improvement on the double breaker system to effect saving in the number of circuit breakers. For every 2 circuits, 1 spare breaker is provided: Two feeders are fed from two buses via their associated circuit breakers and these two feeders are coupled by a third circuit breaker which is called tie breaker. During failure of any of the two feeder breakers, the power is fed via the breaker of the second feeder and main breaker (tie breaker).

Can I wire nut two black wires together and hook 1 to a breaker?

Not according to the electrical code. It requires each separate circuit to be fed individually from its own breaker. If allowed it would reduce the total capacity of each circuit from one amp per outlet to a half amp per outlet if the circuit was fully loaded.The work around in situations like this is to use a tandem breaker which gives you the capacity of two complete circuits and only using one breaker slot in the distribution panel board.

Is main breaker only powering one half of hot bus because when dryer is on some light on circuits on dead bus work?

Yes, it would appear that one side of the main is open at the fuse, breaker, drop conductors, or transformer.


Why does half of my house have electricity and the other half doesn't with no circuit breakers poped?

as an electrician i would first check the main breaker with a rated voltage tester for voltage i would first ckeck the meter side by placing one tester lead on one of incoming phases or wire and place second lead on the other phase or other wire. i should read 240, or 230, or 220 volts depending on where the taps are in the transformer. if not call the power company. if it does read any of them voltages i would then check the load side of the main breaker by putting my leads on one breaker and the one right below it generally every other breaker is a different phase again i should read 240 volts or close. if not the main breaker may be bad. if you know what breaker or circuit its on you could test it by placing one lead on the screw where the wire is and the other on the neutral or ground bar here you should read 120 volts or close if not breaker is bad. it maybe as easy as tightening the screw or screws so shut the breaker off first and then tighten.


Can you install a main electrical panel in a half bath?

No! Panels are strictly forbidden in bathrooms of any kind. In the NEC, a half bath is a bathroom just as much as a full bath.

What is breaker and a half?

one and a half breaker scheme the same as N-1 scheme. means if you have two BUS you 3 breakers each bay between it protecting your 2 connected loads or transmission lines. meaning if fault detected in a particular line only two breakers will trip isolating the faulted line and will not affect the adjacent line or load.

What is one half breaker scheme used for 400220kv substation?

a method of interconnecting several circuits and breakers in a switchyard so that three circuit breakers can provide dual switching to each of two circuits by having the circuits share one of the breakers, thus a breaker and one-half per circuit; this scheme provides reliability and operating flexibility, and is generally used at 500 kV when more than five lines terminate in a substation.

Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?

Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
