Can an NQOD panel with a vertically mounted MAP or MHP main breaker be converted from bottom to top feed and vice versa?

Yes.

******TURN OFF ALL POWER TO PANELBOARD FIRST*******

1. Rotate the entire interior assembly (including the main breaker kit) 180 degrees. Remove screws (7/16-14 X 1) from hard bus connectors in main breaker.

2. Remove screws holding the main breaker to the mounting pan (5/16-18 X 4-1/2) and slide breaker away from connectors.

3. Rotate the main breaker 180 degrees so the on and off symbols are in the correct locatin. (ON position must be up.)

4. Move main breaker lugs to either the line end or load end to receive the incoming conductors. Torque lug mounting screws to 180 IN lbs. (For TOP FEED, the lugs should be located at the ``ON`` end of the breaker. For BOTTOM FEED, the lugs should be located at the ``OFF`` end of the breaker.)

5. Slide main breaker onto connectors, re-attach to mounting pan with 5/16-18 X 4-1/2 screws (torque = 125 - 155 IN lbs) and re-attach to connectors with 7/16-14 X 1 screws (torque = 240 - 300 IN lbs).

6. Any sub-feed breaker(s) must also be rotated in a manner similar to the main breaker so on and off symbols are in the correct location. ON position must be up.
