There are 3 cases in C.B. paralleling:
1. Both Circuit breakers of same current ratings with same time settings.
2. Both circuit breakers of different current ratings
3. Both Circuit breakers of same current ratings with different time settings.
Case1: Any of the C.B.trips (depending on CT characteristics as no two CTs' can have same characteristics)
Case 2. The one with lower current ratings would trip first.
Case 3: The one with lower time settings would trip earlier.

How are quad circuit breakers used?
This would typically be seen in older residential installations where the service was of such a high amperage that the mains required larger breakers than were available (for that panel). Placing two breakers in parallel allowing sharing of the load. Two breakers per (split) phase would total four breakers. Two breakers of 50 amp rating each (in parallel) provide (generally) 100 amps of protection. Two sets of two would provide mains protection for a 200 amp service.
What are the two kinds of electrical circuit?
There are four types of circuit: series, parallel, series-parallel, and complex.
What circuit is a circuit in which electrical current has more than one path to follow?
A circuit that has more than one path for the current to flow is a parallel circuit. The circuit must have two or more paths to be considered parallel. A circuit that has only one current path through multiple components is a series circuit.
What is the difference between a series circuit and as parallel circuit?
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
A circuit that has two or more branches for electrons to follow is?
series circuit

What is a circuit with two or more branches for current to flow called?
Parallel circuit
A circuit that has two or more branches for electrons to follow is a?
parallel circuit.
How many circuits in the parallel circuit?
parallel circuit - a closed circuit in which the current divides into two or more paths.The circuits in a parallel circuits there are two or more circuits.
What are the two kinds of a circuit?
series circuit and parallel circuit
What protects against circuit failure?
Two examples of how to protect against circuit failure are fuses and circuit breakers.
Where is the circuit breakers in 1994 Chevrolet a pick-up?
There are two circuit breakers in the fuse block under the left side of dash. They are aluminum and rectangular. rbamber
What happens when two wires are connected?
Wiring to the circuit breakers is 220 volts. The circuit breaker box has 2 110 Volt lines. If you connect two black lines together from one side nothing happens. If the these two black wires are from different circuit breakers you may have a safety issue by back feeding the electricity. If you connect 2 different 110 volt lines you will end up with a short. This ends up as a 220 volt short.
What is parallel curcuit?
A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
What is a parallel series?
There are four categories of circuit: series, parallel, series-parallel, and complex.As its name suggests, a 'series-parallel' circuit is a combination of both series and parallel elements.
What circuit protector?
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
