Wiring for Current That Goes Into the Electrical Box How To Upgrade An Existing 3 Follow the steps offered by your tester that best align with the way your current circuit is set up. The easiest way for a homeowner to test the direction of their live current is to track the flow using a non-contact voltage tester. The live black wire is spliced to run to the switch and the white wire is also connected to the switch but runs back to and is attached to the electrical box. The white wire from the electrical panel is wired to one side of the light. ![]() If the line carrying live current comes into the light fixtures electrical box first, the circuit will be wired so the switch interrupts the current. Flipping the switch interrupts the flow of electricity to the light, turning it off and on. The live black wire from the power source travels through the switch to the light. If current comes into the switch before it goes to the light, the neutral white line from the electrical panel and the white line that leads to the light will be spliced together and capped. How can you tell which way the current flows? Users can easily add 3-way lighting control without any wiring at all.
