Up to 15A at 125V according to Switchcraft. Or  about the same as that plugging strip.

Lots of ways that could not end well!!

In looking at it I want to say that is the male XLR on the end of the cord.

If there's one you know there has to be more of those in the building, were are the rest of the cords going and what's on the end of them.

Make your self a note to check what's on the other end of an XLR cable someone hands you if you are ever working in there!

Interestingly, decades ago Ampeg used a 4-pin XLR connector on their SVT bass rigs between the 300-watt head and the 8x10 speaker cabinets. And so did Vox on some of their passive column PA speakers.

Actually 20 plus years ago Martin and Turbosound both used standard XLR connectors on their speaker cabinets.

As did Bose. Back then mic cable was usually 8412 which had 18ga conductors. The braided shield was about double that. Use pins 2+3 as hot and pin 1 as cold and you have about a 14ga speaker cable. In a world where a 200W amp was huge.

200 watts into 8 ohms is about 40 volts - slightly safer than line voltage. :)
