TN system.
Customer has 16A breaker from CU which supplies FCU to a boiler, but it also supplies a IP66 external box feeding SWA to garden shed DB.
Since the circuit from the 16A breaker doesn't supply ONLY the SWA to the shed DB, (it supplies also end equipment directly - ie the boiler) - then is it technically a distribution circuit?
(What the real question boils down to, is at the far end of the SWA in the garden shed where it terminates at shed DB, am I looking for 5 seconds or 0.4 disconnect time)?
