If there is one thing I have learned over 23 years in the entertainment business is it never hurts to have a backup plan for a backup plan. Sometimes we arrive at a venue and things are not as they were described. We have a clear requirement of 2 - 20 amp 110V circuits in our contract but sometimes people see outlets and think they are good. Well if those outlets are all on the same circuit that is not the case.
We ran into this over the past weekend. Not only that but we had dirty power (lots of interference). Our equipment is on filtered power but that doesn't help with inductive loads on the same circuits. We ended up pulling a generator out of our truck to make sure we could make it through the evening. While this helped our power issue it did not help with the fact that the power we were using was dirty and at the end of a very long run so our 20 amp circuit was really at 14 amps because of the long cable run that the client had to their building.
The point of this post is to say that if you don't prepare it will affect how your customers view the services you provide. Do the best you can with what you got and people will remember you and your performance. Try and think for your customers. Remember you are the professional so act like it.
