Hi, I work in a physics lab at the University of Maryland. We have a piece of equipment that has a 5-20 plug and, according to the manual, draws up to the full 20 A. We need to move it a few feet, and will need an extension cord. Does anyone know of a good source for extension cords with 5-20 plugs and receptacles???
The only example I've found with Google is this:
The only alternative I can think of is to buy a length of 125V/20A three-conductor cable and splice it onto the current power plug for the equipment. However I don't know how to safely splice such cable. Does anyone have any pointers on how to do this?
Thanks, Dan Lenski University of Maryland
