Is a hot spot bad?
A hot terminal connection affects your system in a couple of ways: 1. It is a power loss. You are paying extra in your electrical bill for all hot connections. The electrical meter does not care whether the power is going to turn a motor or heat the air. Therefore, a hot connection reduces plant efficiency. 2. Failure. Most damage occurs when the electrical connection actually fails. The arc that is caused when the connections separate will melt most metals. A connection that would have cost $200 in parts and labour to repair could cost the owner in excess of $500,000 in damage. 3. The fire caused by the failure could destroy an entire complex.
