Webb25 apr. 2024 · A radial circuit is an electrical circuit where the feeders to each socket is taken directly from the consumer unit or distribution board (DB) or circuit Breaker (CB) like a 20A MCB. A ring circuit is an electrical circuit which has two feeders both come from the same 32A MCB or RBCO in the consumer unit, and head off to different ends of a ... WebbPrimary-Selective System. a. This system offers a higher level of reliability and flexibility than the simple radial system. b. Primary-selective systems have redundant feeders fed from two separate power sources, so only half of … Webbthe main circuit breaker in a simple radial system. This method is also applicable to double-ended systems where a mid-point grounding electrode is employed. For this mode of sensing, a single current sensor mounted on the equipment-bonding jumper directly measures the total ground current flowing in the grounding electrode conductor. gtwn4250d1ws parts diagram
