which one is better for lighting:a20Afuse or a15Acircuit breake?why?
Answer (1)
A 15A circuit breaker is better for lighting than a 20A fuse. Lighting circuits usually use low current (often under 15 amps). Using a 20A fuse might allow too much current to pass through before it trips, which could overheat the wires and start a fire.Circuit breakers are safer and reusable—they trip off when there's a problem, and you can reset them. Fuses need to be replaced every time they blow.A 15A breaker is properly matched to the typical wire size and load used in lighting systems, making it safer.Use a 15A circuit breaker for lighting because it offers better protection and is designed for lower current loads.
