E. IN BLOCK OR CONCRETE WALLS TO REMAIN, PROVIDE STAINLESS STEEL BLANK

COVER PLATES FOR DEVICES REMOVED.

F. WHERE CIRCUITS ARE REMOVED BACK TO PANELS, ASSOCIATED BREAKERS WILL BE

UTILIZED FOR NEW CIRCUITING OR LABELED AS SPARE.

G. DEMOLITION SHALL INCLUDE REMOVAL AND OFF-SITE DISPOSAL OF MATERIALS. DO

NOT ABANDON IN PLACE ANY ELECTRICAL COMPONENTS UNLESS OTHERWISE NOTED

ON DRAWINGS.

H. UNLESS OTHERWISE NOTED, ELECTRICAL ITEMS SHOWN HEAVY DASHED ( )

SHALL BE REMOVED AND ELECTRICAL ITEMS SHOWN LIGHT SOLID ( ) SHALL

REMAIN.

I. THE EXISTING FACILITY WILL REMAIN IN OPERATION DURING RENOVATION.

INTERRUPTION TO THE EXISTING BUILDING ELECTRIC SERVICE MUST BE
