Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) - Part 3: Electrical safety requirements

IEC 63044-3:2017+A1:2021 specifies the electrical safety requirements for HBES/BACS. In addition, it defines safety requirements for the interface of equipment intended to be connected to an HBES/BACS. It does not apply to interfaces to other networks.

NOTE: An example of other networks is a dedicated ICT network covered by IEC 62949.

This document covers the following requirements and compliance criteria:

  • protection against hazards from the device;
  • protection against overvoltages on the network;
  • protection against touch current;
  • protection against hazards caused by different types of network;
  • protection of the communication wiring against overheating caused by excessive current.
