Short answer: Choose an industrial electrical enclosure by defining the installation environment, mounting arrangement, usable internal space and required documentation. Match those needs to an exact model and configuration before comparing prices. A cabinet that fits the components can still be unsuitable for the location or difficult to maintain.
Canadian projects can combine very different conditions: an indoor automation room, a damp utility building and a weather-exposed equipment pad should not begin with the same enclosure assumption. Start with the site conditions, then narrow the product family.
Start with a written environment description
Record whether the cabinet will be indoors or outdoors, whether washdown occurs, and which dusts, chemicals or salt sources may reach it. Describe conditions during shutdown as well as normal operation. A building that is warm during production may cool considerably when equipment stops.
Use that description to establish the project rating and material requirements. Tekpan's enclosure rating guide provides background; the selected model's documentation remains the reference for procurement. Keep environmental protection separate from the final assembly's approval requirements.
These are starting points for evaluation, not blanket application approvals. Product selection still depends on the exact configuration and installation conditions.
Size for installation and maintenance
Build a component layout showing cable ducts, terminals, power supplies and the largest cable bends. Include device removal paths and door-mounted equipment. Check usable mounting-panel dimensions rather than relying only on external height and width.
Define future capacity in terms of expected equipment: another I/O module, an additional feeder or a communications gateway. An unexplained spare-space percentage is less useful than a drawing showing where those additions will go.
For an illustrative indoor machine-control project, the first layout might favour a wall cabinet. If field wiring fills the bottom cable zone and leaves no access to terminals, a larger cabinet or different arrangement may be justified before fabrication begins.
Assemble the selection record
Keep one document containing the model code, material, required rating, mounting arrangement, heat-load assumptions, accessories and delivery destination. Attach the relevant drawing and identify who will confirm the completed panel's acceptance requirements.
A quote based on this record is easier to evaluate because the supplier and panel builder are pricing the same assembly. Record exceptions explicitly, including any accessories that are excluded.
Frequently asked questions
Should every Canadian installation use stainless steel?Material should follow the exposure assessment. An indoor dry location and a corrosive process area have different needs; stainless steel alone does not settle the rating or accessory questions.
Is external cabinet size enough to approve a layout?
No. Verify internal mounting space, depth, cable entry, thermal design and maintenance access on the selected drawing.
