Open the CIPO recordAbstract From the Canadian patent
A combination panelboard-switchboard housing accepts plug-on connection with a plurality of modular electric switch-circuit breaker enclosures. The modular enclosure accepts circuit breakers or electric switches which can be field-installed with minor alteration to the enclosure. The modular switch enclosure further accepts a wide range of ampere ratings within a standard enclosure size. A mechanical latch arrangement on the bottom of the modular enclosure prevents the modular enclosure from being removed from the panelboard-switchboard housing. Controlled temperatures are achieved within the housing by optimized circulating air flow.

Why it's free to use
- Filed February 22, 1990 and granted February 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
