Burn Up the Myth:  Switching Circuit Breakers

Q:  I am curious about your opinion on a theoretical situation. Say, for example, I have a 277/480V, 400A panel which provides power to HID lighting fixtures.  Assume that the upstream transformer is the service transformer for the building-it might be on the large side, say 2000kVA.  The available bolted fault current might be pretty large (40k-45kA).  Would you recommend PPE in this situation, and if so, how much?-TG

Q:  Does it matter whether smaller breakers (say 20A) are switched individually or you are switching the 400A panel all at once?

 

Q:  Assume the same system, but with an 800A circuit breaker in the main switchgear serving one load.  Would switching this larger circuit breaker carry the same hazard or a greater one?

 

Q:  Does the engineering judgment depend, in your opinion, only on available Ibf (bolted fault amperes) or on available calculated Iarc/incident energy (arc incident amperes)?

 

Q:  An issue came up recently at a site where I’m working where the company contracted someone to perform an arc flash study.  The contractors were observed in an electrical room without any special electrical PPE on and were opening the hinged cover of a panel to expose the operating switch portion of the circuit breakers (the main cover remained in place).  My feeling is that this activity falls under “Opening Hinged Covers (to expose bare, energized electrical conductors and circuit parts)” in Table 130.7(C)(15)(a), p. 36,  of the 2012 NFPA 70E.  The contractors’ opinion was that they were not involved in “electrical work” and therefore were not subject to the 70E standard.  The argument is that as long as all of the knockouts are in place for the circuit breakers there may be little or no potential to contact bare, energized electrical conductors and circuit parts. However, I have seen many electrical panels in which the knockouts are missing or that cardboard or tape is covering the knockout locations.

Clarification on Previous Burn Up the Myth Article  

The intent of Pat’s article  last month was the focus on outer shells, specifically high visibility vests.  There is no prohibition on layering clothing for arc protection, but just adding up layers or using the old 2004 HRC layering schemes is no longer allowed.  A few readers interpreted the statement that you couldn’t add up layers to mean you couldn’t test layers. This is not the case. 

 

Non-FR underlayers or arc rated underlayers are allowed and may be counted toward protection IF they are tested though non-FR underlayers are a risk in case of ignition.

 

The language in NFPA 70E was changed to prevent saying 4 cal/cm² over cotton is HRC2.  That is the intent but it could be clearer in the standard. 

 

Annex M clarifies the intent of this section and many multilayer systems have been tested to address the needs of end users looking to have easy to use systems for protection in arc flash events.

ASTM Standards Tracker Alert:  F887
ASTM International LogoA new copy of the F887 – Standard Specifications for Personal Climbing Equipment is now available.  It has been editorially changed, and is now available as F887-12e1.  

This standard covers the specifications and qualification testing of the following:

Climbers, Climber straps, Climber Pads, Climber Footplates, Body Belts, Positioning Devices with Locking Snaphooks/Carabiners, Wood Pole Fall Restriction Devices (WPFRD), Harnesses, Shock Absorbing Lanyards.
 

These devices are used by workers in the climbing of poles, trees, towers, and other structures. Minimum performance criteria for arc resistance of harnesses and shock absorbing lanyards are included for workers who may be exposed to thermal hazards of momentary electric arcs or flame.

December Survey

Does your company have a documented preventative maintenance program for electrical devices?

 

Does it follow NFPA 70B?

 

Does it follow NETA-MTS 2011?

 

Do you test, clean, and calibrate main breakers at least every 3-5 years?
