Frequently Asked Questions
How long does a switchboard upgrade take?
Most residential upgrades take around 3–5 hours depending on complexity. Commercial installations may take longer due to larger circuits or load balancing requirements.
Do I need an upgrade if I still have ceramic fuses?
Yes. Ceramic fuses are outdated and unsafe by today’s standards. Upgrading ensures proper RCD protection and helps prevent electrical fires.
Can you install surge protection at the same time?
Absolutely. Surge protection is often installed as part of a switchboard upgrade to protect your property from power surges and lightning strikes.
Are your upgrades certified?
Yes — every FMZ Electrical upgrade includes testing, compliance certification, and a Certificate of Electrical Safety upon completion.
