Scope:

1.1

These fuseholders and devices accommodate fuses to be employed in electrical circuits and are intended to be used in accordance with the Canadian Electrical Code, Part I (CE Code Part I), CSA C22.1, the National Electrical Code, NFPA 70, or the Mexican Electrical Code, NOM-001.

 

1.2

These requirements cover:

 

a) Fuseholders for fuses intended for use with fuse classes covered in the ANCE NMX-J-009-248; CSA C22.2 No. 248; and UL 248 series of standards, Parts 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15; and

b) Fuseholder accessories (such as covers, indicators, adapters, etc.).

 

1.3

This Standard and its subsequent Parts establish the characteristics, construction, operating conditions, markings, and test conditions for fuseholders.

 

1.4

The titles of the Clauses in this Part 1 correspond to the similarly titled Clauses in the subsequent Parts. 

Project need:

To maintain alignment with North American requirements and support innovation in the field of fuseholders by providing requirements for the construction in the Canadian context.

This proposed amendment is being developed at the request of manufacturers, certification bodies, and the CANENA Technical Harmonization Committee 32B. It will provide the industry with the latest general requirement for fuses. These requirements are intended for use in parallel with other requirement for specific classes of fuses as described in other Tri-national documents within the CSA-C22.2 No. 4248 series standards.
