FAQ
Q: Does this switch include fuses?
A: No, this is a non-fusible transfer switch. It is designed to be protected by upstream circuit breakers in your main panel or generator panel.
Q: What size generator can I use with this 100 Amp switch?
A: While the switch is rated for 100 Amps, the actual load capacity depends on your generator's output. This switch is typically used for "whole house" backup in smaller homes or for "essential loads" sub-panels in larger homes. Always ensure your generator's output breaker matches the application requirements.
Q: Is professional installation required?
A: Yes. Working with 100 Amp service and 240V power is dangerous and subject to strict local electrical codes. A licensed electrician must install this transfer switch to ensure safety and compliance with NEC (National Electrical Code) standards.
Q: What wire sizes are compatible with this unit?
A: The lugs are designed to accept a wide range of wire gauges: 14 to 1 AWG for Copper wire and 12 to 1 AWG for Aluminum wire.
Q: What is the difference between NEMA 3R and NEMA 1?
A: NEMA 1 is for indoor use only, protecting against contact with the equipment. NEMA 3R (which this unit is) provides protection against rain and ice formation, making it the correct choice for exterior mounting.
