so, what happened? new here, but everyone failed to mention the safe alternative without changing the breaker, using gfci’s. op could have taken one hot wire and the neutral and made a 110v circuit, then hooked it up to a gfci in a wall mounted box to cover the exposed screws. that would have made it safe and about 15a i believe.
