Ordered a custom pad for the bench. Put on temporary pads and moved the bench inside to try various configurations. Last week we had all of the 15 amp breakers trip so I contacted SECO ( our local power company) and they directed us to the village's warranty department. They were aware of the problem and an electrician is coming this afternoon to replace the breakers. Seems like the original breakers can be tripped by ham radio signals. Also having an electrician coming to the neighbors house because she had the exact same problem.
