10-7-3 Outlet Test - Wiring Arrangement - USA & Canada
Test all outlets in the area for proper grounding and wiring arrangement by plugging in the neon outlet
tester and noting the combination of lights that are illuminated. Any problems found should be reported
to the hospital immediately and the receptacle should not be used.
NOTE: No outlet tester can detect the condition where the Neutral (grounded supply) conductor and
the Grounding (protective earth) conductor are reversed. If later tests indicate high leakage
currents, this should be suspected as a possible cause and the outlet wiring should be visually
inspected.
10-7-4 Grounding Continuity
Measure the resistance from the third pin of the attachment plug to the exposed metal parts of the case.
The ground wire resistance should be less than
0.2 ohms. Reference the procedure in the IEC 601-1.1.
