Compare
Ranked #1 based on expert reviews, user sentiment, and value analysis.
Pros
- Complete kit with cord and inlet box
- Built-in wattmeters for load balancing
- US-made with long parts support
Cons
- Six circuits will not cover a whole house
- Installation still merits an electrician
Don't buy this if…
- Do not buy a 30-amp switch for a generator with a 50-amp outlet, since you will strand capacity you paid for.
#2
9.2
Excellent
Consensus
Compare
Ranked #2 based on expert reviews, user sentiment, and value analysis.
Pros
- Whole-house 200-amp coverage
- Service-entrance rated
- Weatherproof outdoor enclosure
Cons
- Requires a compatible standby generator
- Professional installation is mandatory
Don't buy this if…
- Skip automatic switches entirely for portable generators, because ATS units are engineered for fixed standby systems.

Excellent
Consensus
Compare
Ranked #3 based on expert reviews, user sentiment, and value analysis.
Pros
- Ten circuits cover most essentials
- Same proven Pro/Tran platform
- Kit includes everything but labor
Cons
- Larger box needs more wall space
- Still capped at 7500 running watts
Don't buy this if…
- Do not overload circuit assignments beyond generator capacity, since the switch enables but cannot create wattage.

Excellent
Consensus
Compare
Ranked #4 based on expert reviews, user sentiment, and value analysis.
Pros
- Whole-panel flexibility instead of fixed circuits
- Upgrade path to automatic
- 50-amp capacity for big portables
Cons
- Load discipline falls on the user
- Costs double a 10-circuit switch
Don't buy this if…
- Avoid whole-panel manual switches if household members will not manage loads, because tripping the generator mid-outage helps no one.

Excellent
Consensus
Compare
Ranked #5 based on expert reviews, user sentiment, and value analysis.
Pros
- Flush-mount capable for finished walls
- 10 circuits at a value price
- Simple toggle operation
Cons
- No wattmeters included
- Parts network smaller than Reliance
Don't buy this if…

Consensus
Compare
Ranked #6 based on expert reviews, user sentiment, and value analysis.
Pros
- Simplest legal furnace backup
- Works with small inverter generators
- Fast DIY-friendly install
Cons
- One circuit only
- Not a whole-home solution
