Extended Product Information

FAQs

Can I install this myself?

No. Installation involves high-voltage wiring and must be performed by a qualified electrician to ensure your safety and compliance with regulations.

What does the 10mA rating mean?

It refers to the residual current sensitivity. A 10mA rating is highly sensitive, providing faster and more reliable protection against shock than standard 30mA residential RCDs.

Is this device waterproof?

It is rated IP66, meaning it is dust-tight and protected against powerful water jets from any direction, making it suitable for heavy outdoor use.

Does it work on any extension cord?

It is compatible with 3G0.75² to 3G2.5² cables. Ensure your cable falls within this range before attempting installation.

Can I use this for indoor DIY projects?

Yes, it provides excellent safety for indoor power tools or appliances, though its IP66 rating makes it overkill for basic household use.

Troubleshooting

Device trips immediately upon plugging in

This often indicates a ground fault in the connected tool or appliance. Test with a different, known-working appliance to isolate the fault.

Device fails to reset

Ensure the power supply is active and check that the internal mechanism is not jammed with debris; if it still fails to reset, the internal fuse or mechanism may be damaged.

Pros and Cons

Pros

  • High-sensitivity 10mA trigger for maximum safety
  • IP66 rating ensures reliable performance in rainy or dusty conditions
  • Easy to integrate into existing cable assemblies
  • Compact and durable construction built for industrial use

Cons

  • Requires professional installation by a qualified electrician
  • Not intended for non-technical users to wire independently
  • Limited to specific cable gauge sizes (3G0.75² to 3G2.5²)

Setup, Compatibility & Care

This device is designed for permanent or semi-permanent cable mounting. Warning: Due to the nature of electrical wiring, this must be installed by a qualified professional to ensure the integrity of the earth connection and proper polarity.

  1. Ensure the power is completely isolated before beginning installation.
  2. Verify your cable gauge is within the 3G0.75² to 3G2.5² specification.
  3. Secure the device housing properly to prevent water ingress at the cable entry points.
  4. Test the device function before initial use.

For care, periodically inspect the housing for physical damage or cracks that could compromise the IP66 seal. If the casing is damaged, replace the unit immediately to maintain safety standards.
