Safe to check yourself
Urgency: medium

What it means

Likely causes

  • Faulty appliance
  • Damaged extension lead or plug

What you can safely check

  1. Unplug the appliance that was running when it tripped, and any recently added appliances, then restart.
  2. If it keeps coming back, stop and call a qualified installer.

When to call a pro

If the safe checks don't clear it, or it keeps coming back, call a qualified installer.

Solar systems carry dangerous voltages. Only do the safe checks listed. If unsure, call a pro.
