3/4.8.3 ELECTRICAL EQUIPMENT PROTECTIVE DEVICES Primary containment electrical penetrations and penetration conductors are protected by either de-energizing circuits not required during reactor operation or demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers by periodic surveillance.
The surveillance requirements applicable to lower voltage circuit breakers and fuses provides assurance of breaker and fuse reliability by testing at least one representative sample of each manufacturers brand of circuit breaker and/or fuse.
Each manufacturer's molded case and metal care circuit breakers and/or fuses are grouped into representative samples which are then tested on a rotat-ing basis to ensure that all breakers and/or fuses are tested.
If a wide variety exists within any manufacturer's brand of molded case circuit breakers and/cr fuses, it is necessary to divide that manufacturer's breakers and/or fuses into i
groups and treat each group as a separate type'of breaker or fuses for surveil-l lance purposes.
The bypassing of the motor operated valves thermal overload protection continuously or during accident conditions'by integral bypass devices ensures that the thermal overload protection will not prevent safety related valves from per-forming their function.
The Surveillance Requirements for demonstrating the bypassing of the thermal. overload protection continuously and during accident conditions are in accordance with Regulatory Guide 1.106 " Thermal Overload Pro-tection for Electric Motors on Motor Operated Valves", Revision 1, March 1977.
