Today i received a call from a nervous manager, "All my computers are out, a breaker is off, can you come right away?"
I asked what is off, and he replied all 15 of my computers, I asked are you sure that only one breaker is off, yes, they are all on two outlets, and there are 6 strips pluged into each other from there.
It appears, that, this past spring, an EC changed his service panel, as he was asked to, the owner was under the assumption, that changing the service panel gave him more power, the EC never questioned the load or asked any questions, just replaced the panel.

This was a good time for the EC to up sell the customer and he missed the chance, and now it appears he lost any future work from this account.
