An RCD (Residual-Current Device) is designed to provide additional protection against the effects of electric shock by automatically disconneting supply before serious physical injury can occur.

It is best and strongly recommended to install an RCD in the following situations:

  • When adding circuits, socket-outlets, lighting points and hand-held equipment.
  • When installing EV chargers and underfloor heating cables.
  • When installing electrical equipment, including socket-outlets in damp situations, such as in bathrooms, laundry, pool and sauna areas.
  • During any house renovation or switchboard upgrade.

Our Electrical Safety Check services can:

  • identify if any electrical circuits or equipment is experiencing an overload
  • reveal any electrical hazards
  • identify non-compliant “do-it-yourself” home handy work
  • highlight any lack of bonding or earthing, etc.

Depending on the electrical systems in your home or business premises, our team will thoroughly work through all areas to ensure that there are no risks or issues. If problems are identified, each issue will be noted and a practical repair solution will be recommended.

We recommend that you have an electrical safety check carried out if:

  • you are purchasing a property that has been occupied.
  • the property is more than 25 years old.
  • if you are concerned about how certain equipment may have been installed.

These are the times when upgrading the switchboard needs to be non-negotiable:

  • Prior to renovating all or part of your home.
  • Before installing a solar power system – solar PV systems require a level of safety not provided in older fuse boards. Also, minor upgrades or additions may be required if there is not enough space in your current modern switchboard for the extra circuit breakers needed by the new solar system.
  • If you are adding a large appliance which requires a dedicated circuit or increased power supply such as hot water systems, air conditioning, pool filtration equipment, an oven or stove, etc.
  • When adding power points or extending the electrical wiring to include more power points.
  • If your home experiences frequent tripping of circuit breakers or fuses.
  • If electrical components, wiring or power points show signs of overheating such as scorch marks, give off smoke, or burning smells.
  • If you can hear buzzing noises or other sounds from the fuse box or other electrical components.
  • You’ve had an electrical fire.
  • When upgrading or replacing the electrical meter.
  • When rewiring all or sections of your home electrical system.
  • If the current switchboard is full with no room to fit additional circuits.
  • If 3-phase power required for a large appliance.
  • If the switchboard needs to be moved.
  • After purchasing an older home. Upgrading is a smart idea because you don’t know the history of the electrical system, better to start safely. In fact, we would recommend a full electrical safety inspection to ensure the whole electrical system is safe for you, your family, and anyone working on your property.
