Where single conductor cables comprising each phase, neutral, or grounded conductor of an alternating-current circuit are connected in parallel as permitted in 310. Joining conductors in parallel is like having two or more smaller conductors connected at each end to make one larger conductor. The single input supply (phase and neutral) is connected to this main MCB. When this MCB is turned on all other MCBs will get the power supply. Single-pole MCBs are used for the output loads. The isolator is used to OPEN and CLOSE the lines manually, which is the main switch of the electrical system. The RCCB is a device used. These are usually connected to thick black or red wires, each carrying 120V in a split-phase system. Verify voltage with a multimeter: each line wire should show ~120V to neutral and ~240V across both hot wires. Load terminals, positioned below the line lugs, distribute current to downstream. What's a neutral?The IEEE defines a Neutral as the conductor that has an equal potential difference between it and all other conductors (hot wires). An example of a neutral wire would be the white/gray wire of a single-phase 120/240 volt system or a three-phase 4-wire Wye system, Figure 1-1. 10 (G) (2) through (G) (6).
