5 Things to Know About Using a 16-Gauge Cord for a Shop Vac

A 16-gauge cord is fine for a 7-amp shop vac at 25 feet The cord is rated for 13 amps continuous, so you are barely over half capacity. Voltage drop is negligible at that length.

Ignore the internet hype about needing 12-gauge cords for everything Unless you are running a table saw or a compressor that spikes hard on startup, 16-gauge is perfectly safe for a shop vac.

Always fully unroll the cord before use Coiled up, it can heat up faster. This applies to any gauge, not just 16-gauge.

Save your money for better things Skip the expensive 12-gauge cord and spend the $20 on a new pack of filters instead.

Check your vacuum’s amp rating first If your shop vac draws more than 10 amps, consider a heavier gauge. But for typical 7-amp models, 16-gauge is more than enough.
