30 Amp Dryer Plug Temporary Use For 240 Volt Saw

[Miss the Pontiacs]

I have to get power outdoors for a 240 volt stone saw.
Quickest way would be to the dryer 30 amp outlet. The fellow that lent me the saw has a number of pigtails.
The one I’ll show of a pic of is or was a 30 amp plug with the one connector cut off. So I’m planning on going this route.
Probably not to code but only to be used on this one stone job.
I don’t see much difference doing this or going back to the panel and pig tailing across the breaker.
I’m just a little apprehensive since this is on a new build and the electrical inspector just gave us a pass less than 3 weeks ago. I’ll probably be cutting for a day or two.
Appreciate your input.

what he did was cut off the neutral so it would fit either a dryer or stove receptacle.
when I did hardwood floor refinishing we used the same set up to get 240 to the drum sander . 99% of the time we used the stove outlet.
we should have used a breaker or fuse as the sander was 30 amp @ 240, but a 40 amp is not that far out of line, plus we were always there when it was running of course

Dont need neutral for a 240v motor, however if the motor doesnt have integral overload protection then youre playing with fire if its rated for a lower amperage circuit.

Can you post a pic of the motor nameplate.

@The Cobbler The owner had no problem when I told him I was going to use a 30Amp. The reason for the dryer is that is closer to the back door.
@wyliesdiesels Can’t get. Apic any more tonight but like I mention to The Cobbler he had no issue with the connection. I did notice it was an old Baldor. The owner was a stone mason that just turned 75 so this wasn’t his first stone rodeo. I’ll take some pics of his well used saw tomorrow. I just wish it was a wet saw as I’m going to be in a stone dust cloud if there is no wind.

I use 240 Volt Range Plugs for both my WELDER and TABLE saw

@nadogail For sure now I know I’m going with experience Thanks.
I don’t know what it is but as I get older I have more of a tendency to err on the side of caution. Guess I’m trying to extend my time on the planet. Sure wasn’t like that years ago.

which type of range plug? 10-50 or 14-50? does the saw motor have integral overload protection?

The saw has built in protection. It's fine.

Appreciate the assistance, but how do you know this from the info plate?

Don’t know how I missed something so obvious. Was looking in the well worn details for some special spec.
