An old security light failed & I've bought a replacement - 300W. Instructions say it should not be wired into the lighting circuit, but into a fused switched spur on the ring main.
The old light was wired in 1.5mm twin & earth through a light switch & into the lighting circuit (which has a 6amp circuit breaker). The security light is under a carport & all the wiring outside is under the carport where it is protected from the rain.
Is it safe simply to replace the light using this wiring arrangement? (The total load on the lighting circuit is well within its capacity.) If not, can I use the existing 1.5mm cable & light switch, & just add a fused spur connecting to the ring main?
