Question: Could you please advise on the correct way to label circuits running off a three-phase distribution board when using both single- and three-phase circuits? For example: 1L1, 1L2 AND 1L3 would be one three-phase circuit using a three-phase breaker, 2L1 is a single-phase circuit using the next available way on the distribution board etc.
Answer: Our distribution board labels allow you to mark each individual way off a three-phase circuit, so it is possible to individually mark each circuit, even when using three single-phase breakers rather than one three-phase device.
