All field wiring shall be tested for conductor resistance.
The loop resistance of each pair or of each conductor and common shall be measured with an accurate ohmmeter.
The resultant measurements must be recorded in the log. Any measurements exceeding 120 percent of the calculated resistance are unacceptable. Abnormal readings shall be corrected, if the fault is at an intermediate terminal box. If it is in a multi conductor cable, the wire/pair shall be identified as "Defective-Open."
การเข้าสายทั้งหมด จะต้องมีการ ทดสอบ ตัวนำ ความต้านทานทั้งหมด
