Question: Does the safety switch (RCD) on your generator protect you?

Answer: No, not in all situations.

Reason: Electricity flows to earth (ground) by the least path of resistance. This is critical especially if the user is in a wet or damp environment.

A safety switch needs to be connected to a tested earth spike that has less resistance than a human body. If a generator is mounted on a vehicle it remains insulated from the earth. This scenario makes a safety switch useless. An RCD requires a tested earth spike to operate correctly.


This safety device offers protection regardless of the earthing environment by combining a standard safety switch with an Earth Sensing Device (ESD). The ESD operates in a compromised earth environment by monitoring voltage and current on the earth circuit. The DUO then isolates power in the event of an electrical fault.
