Residual Current Device (RCD) Testing
Residual Current Device (RCD) testing is a critical safety procedure that verifies the proper functioning of leakage current protection devices. These devices are designed to disconnect the electrical supply when they detect current flowing through an unintended path, protecting people from electric shock.
At Alay Engineering, we perform comprehensive RCD tests using calibrated testing instruments to verify trip current values and trip times, ensuring your protection devices meet safety standards.
What We Test
- Trip current measurement (rated residual operating current)
- Trip time measurement at rated current
- Trip time measurement at 5x rated current
- Non-trip verification at 50% of rated current
- Visual inspection of RCD condition and installation
- Test button functionality verification
Why is RCD Testing Important?
RCDs are the last line of defense against electric shock. Over time, these devices can deteriorate, fail to trip at the correct current level, or trip too slowly. Regular testing ensures they will function properly when needed, potentially saving lives.
Regular RCD testing is essential for electrical safety. Contact Alay Engineering for professional testing and certified reporting.
