My manager had me make up some connections for our electrical panel boxes ( we have 100amp, 60amp and 400amp panel boxes). What he thinks is that we can come out our 60 amp connection (the power from our wall) and hook it up to a 100 amp panel
And operate panel as if it's just a 60 amp panel. This does not sound right to me! If anyone has an answer for me on this I would appreciate it. Dan

Well, what you are describing sounds like you want to have a 60A feeder to a 100A panel. This is fine in theory. My worry is that you have no idea what you are doing and you are going to create an unsafe situation.
This is a convention center. There are some VERY strict rules for working in places like this and some very strict codes. This is considered a "place of assembly" in the eyes of the code. Are you aware of what this means?

I STRONGLY feel you should not be messing with anything electrical in a place like this. Have your manager hire a qualified commercial electrician. PLEASE.

A "Place of Assembly" is any venue that can hold 100 people or more, and is one of the most important Code sections, and is diligently monitored.

Having lived and worked in Connecticut, I can tell you that anyone caught working a Place of Assembly that does not have the proper license, or is properly licensed and does something to violate Code, will be subjected to criminal charges.

This attitude comes from the Hartford circus fire of 1944 that killed close to 200 people and injured 700, and to this day have not identified a young girls body.

I cannot agree with Stan more that a qualified licensed electrician be consulted and hired to do any electrical work in this type of location.

This is one of several types of questions we will not offer free advice.

Too many promoters will spend money, cost no option, to get some spoiled talent their imported bottled spring water, or something trivial, and then not hire the proper tradesmen to do a show safely.
