Full Description


This is the second edition of CSA C22.2 No. 218.1, Spas, hot tubs, and associated equipment. It supersedes the previous edition published in 1989. It is one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.

For general information on the Standards of the Canadian Electrical Code, Part II, see the preface of CAN/CSA-C22.2 No. 0.


This Standard applies to spas, hot tubs, and associated equipment intended for residential and commercial use indoors or outdoors in nonhazardous locations, installed in accordance with the Rules of the Canadian Electrical Code, Part I, and connected
a) permanently to an electrical circuit of 250 V or less (i.e., a maximum of 150 volts-to-ground); or
b) by a factory-provided supply cord, terminating in a moulded attachment plug, to an electrical supply rated at not more than 125 V single-phase and not more than 15 A.
Note: See Clause 4.2.8 for requirements for plug- and cord-connected equipment.

Clauses 4 to 6 apply to spas and hot tubs. Clauses 7 to 9 apply to associated equipment, as follows:
a) Clause 7 - remote packaged units for use with spas and hot tubs;
b) Clause 8 - lighting equipment provided as an integral part of a spa or hot tub; and
c) Clause 9 - electrolytic chlorine and bromine generators.

This Standard does not apply to
a) hydromassage bathtubs (covered in CSA C22.2 No. 218.2);
b) portable hydromassage units;
c) heated bathtubs;
d) hydrotherapy bathtubs or units; and
e) swimming pool heaters.

General requirements applicable to this Standard are given in CAN/CSA- C22.2 No. 0, General Requirements - Canadian Electrical Code, Part II.

In this Standard, "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.
