A 1-pole 100A 347V breaker like the FA17100B can be incorporated into hot tub supply circuits, but Canadian Electrical Code (CEC) requirements for hot tub installations — including disconnecting means, GFCI protection, and clearance distances — must be met. We recommend confirming the full circuit design with a licensed electrician to ensure CEC compliance for your specific application.
