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
