Hi Russell, They are usually my connector of choice for many things, but in this case, they are too large. I considered the mini-XLR connectors, but I've had reliability issues with them. I think that if I chose the wire more carefully so that the strain relief worked better, that might be alright, but I haven't had the chance to test that theory. I also haven't looked at current capacity on them. I've done what Dwayne suggested in the past when using XLR for power. Or I use a 4 pin XLR. I did catch someone once trying to use XLR3 for 120V. I confiscated the adapter, and introduced them to the Powercon connector. It was a no name unbranded XLR as well. I wonder how long it would have lasted before failing.
