for Each Connection (X or Y, W, G) to the 240V Receptacle

If Continuity Not Present

in Any Circuit,

Check Wires and Connections from 120V Duplex to 240V Receptacle

If a Connection is Loose or Disconnected, Reestablish a Tight Connection and Recheck Continuity

If a Wire or Connection

is Damaged,

Replace Electrical Panel

Check for Continuity in

Duplex Breaker

from the Line Terminal to the Load Terminal

If No Continuity,

Replace Duplex Circuit Breaker

Check for Continuity in Each Circuit of the

120V Duplex Receptacle from the Female Socket on the Front to the Terminal on the Back

If No Continuity,

Replace Duplex Receptacle

If Continuity Present,

Replace Electrical Panel
