Welcome to my J.A.M. (Just Ask Mike) Session, a weekly column where I answer your basic electrical questions. If you’re a newbie who’s never plugged in a shore power cord (or ask – what’s a shore power cord?), or wonder why your daughter’s hair dryer keeps tripping the circuit breaker, this column is for you. Send your questions to Mike Sokol at mike (at) noshockzone.org with the subject line – JAM.
Can someone give me a place to purchase a test plug with 50 amp to a Y with 15-amp outlets on each side? I want to test that L1 goes to one side of the Y and L2 goes to the other side. The one I purchased on Amazon sends L1 to both sides. I questioned them about it and they said that is the way they wire it up, which means to test for 110/120 at the end of each side is not possible. I think you mentioned where to get one in a blog post but I can’t find it anywhere. Thanks in advance. —Joe Testa
This one did take me a while to find, so I’m not surprised you’re having difficulty finding one with the right wiring configuration. I’ve just called their tech support desk and they confirm that each of the 20-amp outlets is wired to different hot legs on the male 14-50 plug, so this one should do the trick. You can get it from Amazon HERE.
OK, everyone. Remember that electricity is a useful and powerful force, so we all need to pay attention to safety precautions while using it.
Let’s play safe out there….
