To check if your junction box is grounded, you can use a multimeter. First, ensure safety by turning off the power to the circuit you're testing. Next, set the multimeter to measure voltage. Touch one probe to the ground wire or the metal box, and the other probe to a hot wire or terminal. If the multimeter reads zero voltage, the box is not grounded. Seek professional help if you're unsure or need assistance with electrical tasks.
