UL9540A Approved Kits - Indoor Battery Installation In Dwelling Zones

In Canada, UL9540A certification is required for indoor battery installations in dwelling zones, as defined by the Canadian Electrical Code (CEC). Dwelling zones are areas of a building where people live or sleep, including areas such as homes, apartments, and dormitories. The CEC defines a dwelling unit as "a room or group of rooms forming a single habitable unit equipped and intended for use as a residence by one or more persons, and containing cooking, eating, living, and sleeping facilities."

The CEC requires that indoor battery installations in dwelling zones meet the requirements of Section 20 of the code, which includes compliance with UL9540A for fire performance. Specifically, Section 20 of the CEC requires that indoor ESS installations in dwelling zones comply with the following:

• The ESS must be listed for the intended use and comply with the requirements of UL9540A for fire performance.
• The ESS must be installed in accordance with the manufacturer's instructions, and any additional instructions provided by the authority having jurisdiction (AHJ).
• The ESS must be installed in a location that is well-ventilated, dry, and free from any sources of heat or ignition.
• The ESS must be equipped with a disconnecting means that is readily accessible and within sight of the equipment.
