| Post subject: | working energized ? |
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. |

sorry for not getting back sooner and for posting in the wrong forum. I am talking about Lv and i guess i am wrong about what working hot is. got my answer, thanks |
