The purpose of testing the branch circuit is to identify wiring problems that can lead to personal shock hazards, electrical fires, and equipment performance problems.\n1. Verify the polarity, circuit integrity, no ground, and false ground connection of the power receptacle.\n2.Measure the voltage at the power receptacle.The reading should be between 115.2 V AC and 124.8 V AC.\nNote: Toshiba requires that the voltage be -4% of the nominal voltage of 120 V AC instead of the \u00b110% shown in the instruction manual.\n3. Turn off and on each lane and back office PC one at a time through the circuit breakers while observing all other equipment on that front end to ensure that the power recycling only affects that lane's power.Conventional lane terminals should remain turned on.\nIf you do not uncover any problems or have made a plan for corrective action, plug in the available self checkout lanes, bring them to operational state, and proceed with installation.\nNote: If any of the other circuits power down and back up (terminal or other self checkout lane), that self checkout lane circuit is shared.If deactivation for that lane does not occur, wiring is not correct and is controlled by a conventional lane breaker.Report these conditions to the store manager and engagement manager, who can jointly determine corrective action agreements.\nReturn control of the circuit breakers to the store manger or designee for proper conditioning of the conventional lane front-end breakers, and proceed with the self checkout installation conditioning.\nTroubleshooting Document the possible cause, and inform the store manager or designee that corrective actions must be completed before the self checkout lane can be installed or moved to the new location.\nIf the corrective actions do not correct the problems, inform both the store manager and the engagement manager that an escalation in troubleshooting priority is necessary for sign-off of installation and that entitlement to service agreement contracts will be escalated for review to determine liabilities.

Based on only on the information above, what is the nominal voltage? Repeat the request word for word before giving your answer.
