Sleeping Facilities of a Dwelling Unit Rule 26-722(f)(g) (page 142)
The 23rd Edition of the Ontario Electrical Safety Code / 2002 introduces a new rule that states â€śBranch circuits that
supply receptacles installed in sleeping facilities of a dwelling unit shall be protected by an arc-fault circuit
The Ontario Electrical Safety Code does not define exactly what is meant by the term â€śsleeping facilityâ€ť. In order to
facilitate consistent application of the new rule by all Ontario Electrical Safety Code users in Ontario, the following
direction has been developed.
Sleeping Facility - Includes any bedroom within a dwelling unit intended to accommodate sleeping.
Examples of "sleeping facilities" would include master or other bedrooms. In smaller dwelling units an example would
be a combination living/sleeping room.
Examples of rooms that will not be considered as "sleeping facilities" are kitchens, dining rooms, living rooms,
recreation rooms, bath or wash rooms, hallways and stairways, laundry room or area, utility room or area, unfinished
basement areas, etc.
The Ontario Electrical Safety Code defines a "Dwelling unit" as "one or more rooms for the use of one or more
persons as a housekeeping unit with cooking, eating, living, and sleeping facilities".
The new rule provides an introduction to this new technology, we want to keep the application of the rule simple and
not introduce undue hardship to the building industry.
The intent of this requirement is to protect all branch circuits that supply receptacle outlets in sleeping facilities of
dwelling units to provide additional protection for sleeping people against possible fire.
