Powerful but Needs a Strong Circuit

This saw performs well, but it requires a sufficiently strong electrical outlet. On a weaker circuit, it repeatedly trips the breaker. The exact voltage and power demand in watts or amps needed to run it without tripping is unclear. Overall, the tool is powerful and works effectively when adequate power is available.

Pros
  • + Powerful performance
  • + Works well
Cons
  • − Trips breakers on weak outlets
  • − Unclear power requirements

Powerful Saw for Concrete Cutting Projects

This 5500W saw handles slab and pier cutouts well, running on a 30-amp breaker and 10-gauge cord, though it really needs 40 amps and tripped the breaker twice. It cuts deeper and cleaner than a rented 14-inch gas saw, at least twice as fast. Guide wheels make straight cuts easy, and the water pump sprays ahead of the blade to keep lines visible. The float must be weighed down in the bucket. Water use is high, nearly two 5-gallon buckets per hole, so plan for collection indoors. Reinforced concrete has not been tested.

Pros
  • + Cuts deeper and cleaner than a rented gas saw
  • + At least twice as fast as a gas rental
  • + Guide wheels make straight cuts easy
  • + Water sprays ahead of blade to keep lines visible
  • + Water pump works well
Cons
  • − Needs 40 amps; tripped a 30-amp breaker twice
  • − Float must be weighed down in the water bucket
  • − High water use, nearly two 5-gallon buckets per hole
  • − Requires water management indoors
