Open the CIPO recordAbstract From the Canadian patent
The cross buses extending through side-by-side cabinets in a switchgear assembly are mounted on the metal cabinet frames by supports having a molded body with a bus bar mounting surface laterally spaced from a support mounting surface to form a gap between the bus bar and the metal frame. A planar barrier inserted between the cabinets has a cutout aligned with this gap. The molded support further has a barrier surface which extends across the gap and blocks the cutout. The barrier surfaces of supports mounted on side-by-side cabinets abut and parallel flanges on the molded bodies adjacent the barrier surfaces form grooves in which the planar barrier is clamped.

Why it's free to use
- Filed November 8, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 8, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 8, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
