What fuse does a 10kw heater need?

A 10 kW heater typically requires a fuse rated between 40 to 50 amps, depending on the voltage supply (e.g., 240V or 480V). It's important to check the manufacturer's specifications and local electrical codes, as these can influence the exact requirements. Additionally, the circuit wiring and any other components in the system should be appropriately rated to handle the load safely. Always consult a qualified electrician for accurate installation and compliance with safety standards.
