The diagram below shows the wiring for the surge protectors; which wire, the blue one or the brown one, should be connected to the positive terminal?
According to the wiring diagram of the surge protector, the blue wire should be connected to the positive terminal. In electrical circuits, the blue wire usually represents the neutral wire, while the brown wire represents the live wire; therefore, connecting the blue wire to the positive terminal is in line with the circuit wiring principles. However, it is best to confirm based on the wiring method of the specific device. -
It seems that both brown and blue can be connected properly.
It seems to still be a surge protector from Phoenix. We didn’t distinguish between positive and negative before; just don’t connect the ground wire, that’s all. Haha
Surge protectors do not have a concept of positive or negative; current is discharged from the leads to the ground wire
BK is black for grounding, BU is blue, and BN is brown
