PPE for 120V receptacle?

Discussion in 'Electrical Safety Practices' started by MIEngineer, Jun 4, 2009.

  1. MIEngineer Member

    In NFPA 70E (2009) Table 130.7(C)(9) states "Work on energized electrical conductors and circuit parts of utilization equipment fed directly by a branch circuit of the panelboard" has an HRC of 1.

    Does the common interpretation of this mean that work done on a 120V receptacle requires HRC 1 PPE?

    The energized work I speak of is for troubleshooting or testing. I don't see a reason to perform non-testing energized electrical work on a 120V receptacle.

    As always, thanks.

    This is my interpretation....

    A quick arc-fault calculation will probably reveal that this is fed from a transformer that in less than 125KVA. Since it is less then 125KVA, no arc-fault calculations are required and you can label this as HRC 0.

    Gloves?

    If you speak of Class 0 gloves PPE shock protection for 120v? There are a few opinions on this that I have found in the past. I cannot find the link but, there is a letter of interruption that comments on using gloves on 120v ac. Say for testing a receptacle outlet with a meter. Example of exception was test leads that would stop the fingers from slipping and touching the probe tip and no other components in the area that can be touched etc.. The key I suppose is the prohibited approach area for shock protection. In this case, do not touch.

    A receptacle is a contact device and not utilization equipment.

    MIEngineer,
    This is the link to what I was speaking too earlier it’s not OSHA but is by BNL Electrical Safety Committee interpretation.

    I believe the word PANEL is referring to 3phase 240 volts or less and the device is a panel board say for lighting, heating, hvac etc. As mentioned by Chris. I reach this conclusion because, AF hazard is calculated by using 3 Phase short circuit data in the formulas used to determine the hazard level.

    My interpretation of this is not of a receptacle but a three phase circuit breaker feeding a device such as a heater or HVAC system. And the person is working with such equipment.

    Moreover, the statement by, PAult I agree with. If the exception is met then you must only be concerned with shock hazard.
