II. Components
Parts and assemblies to be reconditioned under Section 1200 Low Voltage Circuit Breakers include but are not limited to:

III Testing and Inspection
The PEARL Section 1200 Low Voltage Circuit Breaker Standard begins with the definition of the term “Reconditioning” as “the process of returning electrical equipment to safe and reliable operating condition based upon the design of the original manufacturer at the time of manufacturing.” This is followed by reference tables used to calculate test results and tolerances and the necessary test equipment required by the PEARL Section 1200 Low Voltage Circuit Breaker Standard. The Low Voltage Circuit Breaker Standard continues with a “Recondition Evaluation,” which is a detailed inspection of all parts of the low voltage circuit breaker, including but not limited to the components listed above.

Section I for PEARL Section 1200 Low Voltage Circuit Breakers begins with reference table identification and identification of the test equipment necessary to complete the standards. The following test equipment is required to perform the testing requirements of this reconditioning standard:

1. Insulation Resistance Test Set (Megohmeter) 1000 Vdc minimum

2. High Current Test Set

One of the following pieces of test equipment is required to perform the contact resistance testing requirements of this reconditioning standard:

1. Digital Low Resistance Ohmmeter (DLRO - 10 amp unit is sufficient.)

2. DC Current Source and a Millivoltmeter

One of the following pieces of test equipment may be required to perform the testing requirements of this reconditioning standard, depending on the accessories:

1. AC Voltage Supply

2. DC Voltage Supply

Section II Recondition Evaluation-Inspection and Testing identifies each component and assembly part that must be inspected to determine the components viability and scope of reconditioning required to bring the component back to original operating condition. Results and notes from the pre-reconditioning inspection and test are recorded in the PEARL Reconditioning Evaluation and Test forms that accompany each respective standard.

IV Reconditioning
Section III Reconditioning Procedures describes how to recondition each component and assembly, beginning with the disassembly of the low voltage circuit breakers down to the major subassemblies. Reconditioning for low voltage circuit breakers includes:

Assembly of the reconditioned components and subassemblies is followed by final inspection and testing. As with all testing, inspection, and reconditioning operations, final inspection and test results are recorded onto the Evaluation and Test forms included with the standard. If a PEARL certified technician follows the reconditioning standard, the low voltage circuit breakers assembly is eligible for a Blue PEARL Reconditioned Quality Seal.
