Capacitors can hold a dangerous charge even after the circuit is de-energized. OSHA specifies a five-minute wait after you disconnect the power to let the stored energy bleed down enough to reach a safer level. During that time the capacitor discharges through its leakage paths and any discharge device, reducing the voltage so you’re less likely to get shocked or suffer an arc flash when you work on the equipment. After the five-minute pause, you must verify zero voltage with a properly rated meter before touching or servicing the circuit. Remember, the exact discharge time can vary with capacitor size and circuit conditions, and larger capacitors may need additional discharge measures, but five minutes is the standard precaution used to ensure residual energy has diminished to a safer level. Treat capacitors as potentially energized until you’ve confirmed they’re safe.
