CD6A0045VRA6XXBD DELTA 45KVA 600-480/277V NEMA3R

To confirm sizing, total up your connected load in watts or VA, then add a safety margin of roughly 20–25% for future growth and inrush currents (especially with motor loads). For example, a 45 KVA transformer can support approximately 36–38 KVA of continuous load under Canadian Electrical Code guidelines. If you share your load schedule with us, our team can help verify whether the CD6A0045VRA6XXBD is the right fit or recommend an alternative KVA rating.

Yes — the NEMA 3R enclosure is rated for outdoor use and protects against rain, sleet, and windblown dust, making it suitable for Canadian outdoor environments including rooftop and exterior wall-mount installations. For extreme cold climates, verify the transformer's minimum operating temperature rating and consult a licensed electrician to ensure the installation meets local CEC requirements, including proper grounding and weatherproof conduit entries.
