Generator Transfer Switch Kits

Generator transfer switch kits let you connect a portable or standby generator to your home or small business safely and quickly during a power outage. By isolating utility power and routing generator power to your breaker panel, a transfer switch prevents dangerous backfeed, protects equipment, and eliminates the hassle of running extension cords through doors and windows.

Choose between manual transfer switches for hands-on control and lower cost, or an automatic transfer switch (ATS) that senses an outage and switches over without you lifting a finger. Options range from multi‑circuit kits that power priority loads like a furnace, sump pump, refrigerator, and lights, to service‑entrance rated switches that can power an entire house.

Sizing is key. Match the amperage and voltage to your generator and panel: common portable setups use 30A 120/240V (L14‑30) or 50A 120/240V (14‑50), while standby systems often use 100–200A ATS units. Look for UL listing, NEC compliance, and the right enclosure rating (NEMA 1 for indoors, NEMA 3R for outdoors).

Useful features include load meters, circuit indicators, load‑shedding modules, and Wi‑Fi monitoring on some ATS models. Many kits bundle a power inlet box and a heavy‑duty generator cord, simplifying installation.

Shopping tips:
- Count and prioritize circuits you need during an outage.
- Verify breaker panel compatibility (brands like Square D, Siemens, Eaton, GE).
- Plan the inlet box location and cord length to keep the generator outdoors and away from openings.
- Choose wire gauge that matches amperage (10‑gauge for 30A, 6‑gauge for 50A).
- Have a licensed electrician install and test the system.

With a properly sized transfer switch kit, you get safer home backup power, faster switchover, better load management, and peace of mind. Explore manual transfer switches, automatic transfer switches, interlock kits, and accessories to build a dependable, code‑compliant generator hookup today.
