AS/NZS 3000:2018 (commonly known as Wiring Rules) brings in a major change for residential applications. It states that additional protection by RCDs with a maximum rated residual current of 30mA shall be provided for all final sub-circuits. This clause applies to three phase circuits for air conditioner, cooktops, hot water systems, pool pumps, etc. that were historically not protected by an RCD.

Here at MJS Electrical Products & Supplies, we stock and sell a few RCBO solutions for 3 phase applications.
