Upgrading your switchboard to one which meets current NZ electrical standards and regulations will improve overall electrical safety within your premise.
We replace existing rewireable fuses with new circuit breakers and residual current devices (RCDs).
Upgrading your switchboard improves overall electrical safety. A switchboard upgrade is when existing rewireable fuses are replaced with new circuit breakers and residual current devices (RCDs).
RCDs constantly monitor the electric current flowing along a circuit.
If someone touches a live wire or faulty appliance, causing the current to flow through their body to the ground, they could receive a severe electric shock or be electrocuted. If an RCD senses any loss of current, where electricity is diverting to the ground rather than through the circuit, it will very quickly shut the electricity off and therefore reduce the chance of serious injury.
Houses built before 1970 are likely to have ceramic rewireable fuse switchboards with rubber and vinyl cabling running throughout ceilings and wall cavities. Unknown to you and your family, these cables are often worn, deteriorated and, therefore, a serious fire risk.
Problems you may have with rewireable fuses…
- Arcing and burning if fuses are not put back properly
- Having to test each fuse to find the one that has blown
- Poor switchboard labelling
- Old Brown switchboard doors often contain asbestos
- If the incorrect fuse wire is installed, there becomes a potential for excessive current flow through cables. This will cause the cable to
heat up, melt and increase the risk of a fire inside the ceiling or wall cavities
Benefits of upgrading your switchboard…
- A safer home for you and your family
- Lower insurance premiums
- Switchboard & wiring that complies with current ASNZS3000:2007 standards
- Correctly labelled switchboard – in the event of a fault, you are able to know exactly what circuit has tripped without touching the switchboard
