Scope
1.1
This Standard applies to panelboards and enclosed panelboards, rated 600 V and less, for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I, to provide overcurrent protection for a number of circuits.
1.2
Clauses 1 to 6 apply to panelboards and enclosed panelboards of other than the service entrance type and apply, unless otherwise noted, to the panelboards covered by Clauses 8 and 9 as follows:
a) Clause 8 - panelboards for service entrance use; and (b) Clause 9 - custom-built panelboard assemblies.
1.3
This Standard covers the construction of the synthetic fuses to be used in the simulated load cycle test on fusible panelboards (see Clause 10).
1.4
In CSA standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
