Can some one help with the deference between a 4 prong 30 amp. 220 electric outlet and a 30 amp.220 NEMA 6-20 outlet. It is going to be the electric plug for a Grizzly 0690 saw ( it comes with the NEMA) Thanks to all

The NEMA 6-20 is a 20 amp rated, 3 wire outlet – 2 hots and a ground. The 4 prong (your dryer outlet?) has two hots, a neutral and a ground.

6-20 is not 30 amps, it’s only rated for 20 amps. If you google NEMA 220v plugs you’ll find a few charts that show pics of each plug, it’s rating, what the prongs looks like etc.
Here’s a good one: http://www.generatorjoe.net/html/web/outlet/quailplug.html
The 4-prong plug is used on things like driers and can actually provide 220v and 110v, the 3-prong only provides 220v. For a better explanation look for “220v 3-wire vs 4-wire”

For the saw all you need is the 3-wire plug, either 6-20 or 6-30 depending on how big a circuit you need (20 amps or 30 amps).

if you use the four wire you can add a 120 outlet to the saw. it comes in handy sometimes.

Make sure you specify to your builder what you want – and he in turn pounds it into the electrician the correct outlet. Not like my builder and electrician, who couldn’t find their butts with all four hands. As a result, I got a dryer outlet in my workshop! Took me THREE explanations with those dodo brains of what I wanted!
