What Separates a Great Reliance Transfer Switch For Generator From a Mediocre One

- Reliability over time — the review count and rating in the table above are your best proxy for long-term durability.
- Right-sized features — paying for capability you’ll never touch is the most common buyer regret.
- Everyday usability — setup friction and daily ergonomics matter more than headline specs.
- Honest value — the sweet spot is where price, build, and features intersect, not the lowest sticker.
The Six-Step Buying Checklist
- Set a firm budget range first — it filters out most of the noise.
- Decide your single most important feature and weight it heavily.
- Cross-check the spec sheet against verified owner reviews, not just product copy.

For reliance transfer switch generator, the figures that matter map directly to your use case; when two picks look close on paper, the owner-review volume above is the better tiebreaker. When two picks look close, let the owner-review volume in the table above break the tie.
Which One Should You Buy?
| If you… | Choose… |
|---|---|
| Run a mid-size portable generator and want the essentials covered with 6 circuits | Reliance Controls 31406CWK 30 Amp 6-Circuit Pro/Tran |
| Prefer a surface-mount 30 amp, 240 volt kit with 6 circuits | Reliance Controls 30 Amp 240 Volt 2 Space 6 Circuit Surface Mount Kit |
| Need extra circuits on a 30 amp generator, such as a second freezer | Reliance Controls 31410CRK Pro/Tran 10-Circuit 30 Amp |
| Also want a 10-circuit layout and a different Reliance model number | Reliance Generator Transfer Switch Kit, 10 Circuits, 310CRK |
| Own a 50 amp generator and want 12 circuits | Nature’s Generator Manual Transfer Switch 12-Circuit 50A |
| Own a 50 amp generator and prefer the Pro/Tran2 line | A510A Pro/Tran2 50-Amp 10-Circuit |
A Worked Sizing Example
Real sizing starts with watts, and watts equal volts times amps. A 30 amp, 240 volt feed works out to 7,200 W, and a 50 amp feed to 12,000 W. The Pro/Tran 31406CWK listing states 7,500 W for the 30 amp class. Now apply a made-up household with these assumptions, which you should replace with the nameplate numbers from your own appliances:
- Refrigerator: 700 W running
- Furnace blower: 600 W running
- Sump pump: 800 W running, plus an assumed 1,500 W extra while the motor starts
- Lights and outlets in living areas: 300 W
- Microwave: 1,200 W
Running total: 700 + 600 + 800 + 300 + 1,200 = 3,600 W. Add the 1,500 W starting surge for the single largest motor and the momentary peak is 5,100 W. A generator with a 5,500 W running rating covers that, and a 6-circuit switch has room for all five loads plus one spare. Add a deep freezer, a well pump, and a second refrigerator and you reach eight circuits, which is when a 10-circuit or 12-circuit model becomes the better fit. A 240 volt load normally occupies two circuit positions, so confirm that in the instructions.
Installation and Safety Sequence
- List the circuits you want to keep alive and write each nameplate wattage next to them.
- Match the switch amperage to the generator output receptacle, not to the size of your main panel.
- Choose an inlet location close to where the generator will sit. The Consumer Product Safety Commission advises running a portable generator outdoors, at least 20 feet from the house, with exhaust pointed away from windows and doors.
- Have a licensed electrician install the switch and inlet, and ask whether your jurisdiction requires a permit and inspection.
- Label each switch position so any family member can operate it in the dark.
- Rehearse the changeover once under good weather, following the order printed in the manual, so the first real attempt is not during an outage.
The purpose of the switch is to prevent utility power and generator power from meeting. Never feed a house through a wall outlet with a double-male cord, since that backfeeds the grid and endangers line workers.
