follows:
j The subject #10 AWC conductor was replaced with a #2 AWG conductor per FCR-E-4052.
A review has also been conducted by Ebasco using the latest issue of the power distribution and motor data sheets (drawing 2166-B-041) to assure safety related cable sizes are suitable for the breaker rating.
Administrative action has been taken to ensure closer monitoring and control of cable j
size design in HPES electrical.
In addition, a design i
guideline has now been issued which requires that cable l
size be verified based on the feeder breaker rating, l
connected load and circuit length, before cable routes and sizes can be released by HPES.
