Are there times when we work with power de-energized it is considered working hot. For example when replacing a motor in kind or with a larger one where wiring has to be done in order to complete the task ? I am sure there are other examples of this work.

I thought that I read that if you changed the condition of a circuit in anyway it was the considered as working hot even if the power was disconnected at the time of making the change.

The reason i ask this is because some QE people are using this as a way to do electrical work when they have not been trained to do any, they are trained to test fuses and verifiy power.

Do you mean when the supply of energy has been verified as disconnected? I don't understand your question.

The circuit is considered hot until you verify that it is de-energized. Once de-energized, new circuit or old, its not hot.

I differ. The circuit is hot until it is isolated, grounded and tested. You are asking in the NESC forum where utility rules apply.

Agreed, if he meant a MV or HV circuit grounding is necessary. If low voltage, then just proof of de-energized and LOTO.
