Principles to be followed when cables are connected in parallel

1. When operating space permits, the selection should be based on a single cable for power supply.

2. If there is no suitable single cable for the temporary power supply project, the original cable can be used for parallel connection.

3. When selecting cables for parallel operation, the specifications and models of the cables must be consistent. Parallel connection of cables of different specifications and models is likely to cause an accident due to excessive load current of a single cable.

4. When the number of cables in parallel is large, if the extension wiring board is used for wiring, the distance between the connectors should not be too small, otherwise it will
Reduce the cross-sectional area of the wiring board and affect its current carrying capacity.

5.Both ends of the parallel cable need to share the same protector. It is not recommended to use multiple low-voltage power supplies.
