RCD testing

A safety switch that doesn't trip inside its rated time isn't really a safety switch. We test push-button operation and actual trip time on meter box RCDs and generator-fed supply, record the measured result in milliseconds, and tell you about anything drifting out of spec before it fails an audit.

• ✓Meter box and generator RCD testing
• ✓Push-button and instrument trip-time testing
• ✓Measured trip times recorded per device
