To determine if your metal box is grounded, use a multimeter. Set it to measure voltage and test between the box and a known ground source, like a metal water pipe. If the reading is zero, your box is likely grounded. Additionally, inspect for a ground wire connected to the box. For safety and certainty, consult a professional electrician if you're unsure about conducting these tests yourself, as improper grounding can be dangerous.
