March 22, 20206 yr I have a new Bader BIII grinder. The motor says 110/220. It is a constant speed, not variable. It doesn't plug in to my 220 outlets (like I use for my MIG and my Plasma Cutter). Too small. And, it doesn't plug into my 110 outlets (prongs to long). But, the plug is the same pattern as both, just different size. I'm far from being an electrician. In fact, I believe that lights come on when you flip the switch, by coincidence. Help!
March 22, 20206 yr If it's truly dual voltage 110/220, there will be an indication of the proper wiring somewhere on the device. Check to be certian how it's wired internally, (either for 110, or 220) Then replace the existing plug with the proper one to fit the proper outlet.
March 22, 20206 yr Outlets/plugs are based on voltage and amperage, that is why they are not all the same, I cant comment on what you have with out photos, and I cant guess with so little information about what motor you have
March 23, 20206 yr how can you possibly know from what little information he gave? you're a better electrician than I am. He said nothing about plug shapes only that it was too long
March 23, 20206 yr Author Here's the problem. My blacksmith shop (fairly newly built) has a 20 amp circuit feeding a drop down (roller type) extension cord. I bought a new grinder with a 2hp, 115/130 volt motor. The plug on the grinder is a Hubbell, HBL5965VY, straight blade, male, industrial/commercial grade, straight, 2-pole 3 wire grounding plug, 15 amp 5-15A plug. The plug has, exactly, the same pattern as do my other power tools; two flat, verticals and a semi-round prong in a triangular pattern with the two flat prongs. The problem is, the plug won't go all the way into the receptacle. My next move is to move the grinder close enough to plug it into a wall plug. If that works, is there an extension cord which will work? The grinder has to sit far enough from the wall that the cord won't reach the wall.
March 23, 20206 yr that is a standard 15 amp plug you listed. there is no reason it shouldn't fit into a normal receptacle is recep on the drop cord clean? IF you use an extension cord make sure its actually rated for 15 amps, most cheaper ones are only safe for 10 to 13
