SUBJECT:
POTENTIALLY DEFECTIVE REFURBISHED CIRCULI BREAKERS-t L
.The enclosed Nuclear Regulatory Connission (NRC) Information Notice (IN) 88-46 i
' describes the circumstances unoer which defective refurbished electrical equip-ment-me'y_heve been supplied to nuclear. power plants.
Our continuing investiga-tion'of the five circuit oreaker companies identified in the IN-shows.that the-l companies:have chipped breakers-to a number of government facilities and agencies.
4 l0ur. review of a san.ple of. invoices indicates that_ generally tne breakers are b
sold to a distributor,:and it was only the occasional shipment direct to the end b
' user that permitted us to identify the final' government destination, i
1.have enclosed a copy of an invoice that identify your agency as the custoner. These. documents represent our review of a selection of records
. spanning.the last two or three years from all of the companies.
As other records
- are reviewed. we will proside any: additional information that comes-to' light.
]
-Howeker, since some of the companies have been in business for as many as 30 j
z years,'a full historical records search will not be possible.
1 The,fiv'e California companies appear to sell surplus new as' well as refurbished breakerr. However, their refurbished equipment may be shippeo irt containers resembling original manufacturer containers.

)
Dear Mr. Franklin:
This letter is provided in response to your letter of July 15, 1988 in which you referred to a newspaper article stating that nuclear power plants may have L
bought used circuit breakers that were falsely labeled as new.
Your letter
. indicates that even new North American circuit breakers are not properly designed to prevent short circuit fires, particularly in residential and commercial installations.
Although you do not specifically mention any problems-in nuclear power plants, we conclude that'your concern extends to them also.
L The information you submitted indicates that your research concentrated on 15-and 20-ampere circuit-breakers. You note that most household short circuits result in a 150- to 400-ampere short and that the magnetic (quick) trips of North American circuit breakers may be set in excess of this range. You state that the thermal'(slow) trip may require several seconds at 100 amperes.
Further, you note that European breakers are designed to magnetically trip at lower ratings than North American breakers.
L Our concern regarding the nuclear power plant circuit breakers that may have l
been falsely labeled as-new, as mentioned in the newspaper article, is with L
their ability to function as they are supposed to do. As we understand it, L
'your concern is'with-the designed magnetic trip settings of North American L
circuit-breakers, particularly that they may not trip fast enough during a short circuit to prevent a household fire. We will attempt to address this concern as it may relate to nuclear power plants.
First, we note that the European-style breakers that you appear to be recommending have not been approved by Underwriters Laboratories, Inc. (UL)'.
One of.the reasons given by UL for'this circumstance is that the interrupting ratings of European breakers are not sufficient for most North American applications. This fact would be particularly significant in a nuclear power plant where the protection of safety-related equipment is a primary concern.
l Second, nuclear power plants have extensive fire protection, fire detection and fire mitigation requirements. These include:
(1)
Identification of fire hazards (2) Automatic fire detection systems (3) Automatic fire suppression systems c

(4 Fire barriers and barricades (5
Separation of cables from combustible material (6
Onsite' fire brigades
-(7) Personnel training and periodic surveillance of cables and equipment (8) Enclosure of cables and equipment In addition to these requirements, nuclear plant regulations also require-rigorous design and testing of electrical equipment.and circuits to ensure a
.high level of reliability of safety systems. The design requires redundancy of electrical circuits and separation of the redundant circuits.
Flame tests, in accordance with Institute of Electrical and Electronics Engineers Standard 383, are required to ensure that cables are fire resistant and will not propagate a fire.
Thus, it is unlikely that a relatively low. amperage short circuit as you described would cause a significant fire.
Finally, experience does not indicate that a fire hazard exists at nuclear plants because of-low-amperage short circuits. Of greater concern are high-amperage faults that are not cleared and that may cause equipment damage or may propagate to other systems.
Finally, designing or setting circuit breakers to trip at five times the breaker ampere rating could result in spurious trips of the breakers during motor
. sta.rting.
Such a trip could disable safety equipment and safety systems when they are most needed to prevent or to mitigate an accident condition.
Although we do not anticipate any significant problems at nuclear power plants from the types of shor 1rcuits7Niescribed, we appreciate the insight you have provided regardi g this phenomena h will consider it in our ongoing safety reviews. We thank yo for your conce_r3/

SUNECT :
P0TENilALLY DEFECTIVE REFURBISHED CIRCUIT BREAKERS The enclosed Nuclear Regulatory Comission (NRC) Information Notice (IN) E,B-46 describes the circurrstances under which defective refurbished electrical equip-ment may have been supplied to nuclear power plants.
Our continuing investiga-tion of the five circuit breaker companies identified in the IN shows that the companies have shipped breakers to a number of government facilities and agencies.
Our reyttw of a sample of. invoices indicates that generally the breakers are sold to a distributor, and it was only the occasional shi ment direct to the end user that pemitted us to identify the final government destination.
I have enclosed a copy of an invoice that identifies your agency as the This document results from our review of a selection of records customer.
sp6nning the last two or three years from all of the companies.
As other records

are reviewed, we will provide any additional infomation that comes to light.
