I don't see a problem with this as long as the current circuit is 10Ga
wiring with a 30A breaker. Note that the 6-30R is a 30A plug. This is
sort of circuit is a little unusual for a table saw, which are usually
connects to a 20A branch.


It is a 20A branch so I assume 12 gauge wire.
Not enough power. 5000W/240V = 21A
You need a 30A circuit. Your plug is rated for 30A. No way around
this one.

The 240 outlet happens to be right below the perfect spot to hang a heater. The heater cord would only have to be 7 feet at the most. I'm hoping to save a few bucks by not installing a new breaker, wire, and outlet.
I doesn't matter. You don't have enough power for it.

Perfect! Thanks for clarifying. Budget calls for a cheap solution, so I need to find something that is no more than 4800W. Someday I'll go big. For now I just need something that can take the chill off better than an office space heater.
