FAQ
- What does a commercial electrical load calculator do?
- It helps estimate service and feeder demand for commercial and institutional occupancies using structured demand factors so teams can document sizing decisions for design, permits, and review.
- Is this suitable for Canadian permit packages?
- The platform produces clear calculation summaries and PDFs intended to support professional documentation. Final acceptance always depends on your engineer of record, AHJ, and adopted code.
- How is commercial load different from residential?
- Commercial projects typically combine diverse load types and demand factors. The commercial workflow in Current Systems is built around that structure rather than single-dwelling rules.
