Nelson Switchboard Market
Nelson's active renovation market and solar adoption drive switchboard upgrades. Many older Nelson homes need board upgrades to support solar inverters and EV chargers simultaneously.
When Do You Need an Upgrade?
Your home likely needs a switchboard upgrade if it has ceramic fuse holders, no RCDs (safety switches), frequent fuse-blowing, or if you're adding an EV charger, solar system, heat pump, or induction cooktop. Older fuse boards simply don't have the capacity for modern high-draw appliances.
What's Included
A full upgrade includes: replace fuse board with modern circuit breaker panel, install RCDs on all circuits, label and test, issue Electrical Certificate of Compliance (eCoC). Must be done by a registered electrician.
