scope:

This Standard specifies electrical requirements for recreational vehicles that are intended to be connected by a cord and attachment plug to a source of electrical supply not exceeding 250 V between conductors or 150 V to ground in accordance with rules of the Canadian Electrical Code, Part I.

This Standard does not apply to 6 or 12 V battery-operated vehicular lighting and brake wiring systems specified in CSA Z240.1.2, provided that the conductors of such a system are not or cannot come in contact with the conductors of the higher voltage system.

The requirements of this Standard are based on the Canadian Electrical Code, Part I (see also Clause 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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. 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. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
