How to Choose, Replace, and Upgrade Your Circuit Breaker Safely?
Learn how to choose, replace, and upgrade your circuit breaker safely. Understand warning signs, safety tips, and when to call a licensed electrician for help.
Upgrading the electrical system in an old home in New Zealand is a smart investment that improves safety, compliance, and energy efficiency. Whether it's replacing outdated wiring, upgrading the switchboard, or adding modern appliances, careful planning is key to a successful upgrade.
DO NOT attempt to replace the main breaker yourself. Call a licensed, competent, and insured electrician to handle this situation. DO NOT attempt to access the meter box, underground wiring/overhead cable, or any equipment owned and/or maintained by your power company. Call your power company if any of their equipment needs service.
To change a circuit breaker, find the main circuit breaker box and locate the defective breaker by looking for a tripped breaker. Next, turn off the branch breaker boxes, the main power, and the individual breakers. Remove the screws holding the circuit panel's face plate, then loosen the screws holding the wires on the defective breaker.
These provisions protect the competitive position of New Zealand and China into the future by ensuring that others who negotiate free trade agreements with China in the future do not end up with better conditions than apply to New Zealand businesses. See Annex 9 for more detail on these provisions.
