BS EN IEC 63044-3:2018

Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS). Electrical safety requirements

Status : Under review, Current   Published : March 2018



This part of IEC 63044 provides the electrical safety requirements related to the HBES/BACS network in addition to the product safety standards for HBES/BACS devices.

It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product safety standard exists.

In addition, it defines safety requirements for the interface of equipment intended to be connected to an HBES/BACS network. It does not apply to interfaces to other networks.


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

This document is applicable to

  • operator stations and other human–system interface devices,

  • devices for management functions,

  • control devices, automation stations and application-specific controllers,

  • field devices and their interfaces, and

  • cabling and interconnection of devices

used within a dedicated HBES/BACS network.

This document covers the following requirements and compliance criteria:

  • protection from hazards in the device;

  • protection from overvoltages on the network;

  • protection from touch current;

  • protection from hazards caused by different types of circuit;

  • protection of the communication wiring from overheating caused by excessive current.
