10.6.3 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.
1 Correct Wiring
2 Open Ground Wire
No outlet tester can detect the condition where the Neutral (grounded supply) conductor and the Grounding
Note
(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.
