Type A - Can be used for general purpose and for equipment incorporating electronic components. Type F - Used for appliances containing synchronous motors and some class 1 power tools. Some air conditioning controllers and other frequency controlled equipment.

Type B - Used for three phase electronic equipment such as inverters for speed control and EV charging where the current is. Most appliances within a modern home will risk producing earth leak faults, so an RCBO on each circuit can eliminate this, yet the distinction between whether a Type AC should be upgraded to a Type A lies in the evolution of residential properties in the coming future.

As we know, when installations which may have DC fault currents are installed, the possibility of a DC component causing a fault on an AC device is highly likely. With legislation in the automobile industry pushing manufacturers to a renewable source of travel and combustion engines soon to be made illegal, future proofing the electrical installation so that it can continue to comply with points B and C of Chapter 31 would mean installing a Type A device.

In this Regulation it requires that protective measures are to be taken against DC fault current greater than 6mA.

This means that at the charger itself a Type B device should be used. This however, will not stop a pulsing DC current arriving at the distribution board and therefore, this device needs to be allocated as a Type A as a minimum requirement and to ensure that the installation can continue to comply with section D of Chapter We believe that an RCBO installation is the safest and most compliant installation available to the installer for residential properties.

The question of whether a Type A should be used or even made compulsory is a matter of affordability and awareness. With the cost of RCBOs now considerably lower than in years gone by and the cost difference between Type A and AC not being a vast amount, future proofing your installations to ensure they comply long after installation would see Type A become best practice.
