From Phil "Ingineer":
"Just add two 120v coil SPST relays to your box and then there is no safety question.
You never know if someone's child might happen upon one of your two cables and pull it out and touch it with bare feet, or touch it and something grounded. If you will not be there 100% of the time guarding it, it's not safe.
In my home-made version I included the 2 relays, total additional cost was under $10. I didn't bother with a meter, but I added a super-bright blue LED and a buzzer that sounds for a few seconds once it "sees" 240v, that way you can easily determine if you've found the right outlets even if you can't see the unit. I included 8' of cord on the two cables, and in most all cases I can find 2 circuits within 16' of each other and still have the cables not take up a lot of space."
