IEC60061-3: 7006-30-2 Plug Gauge for E14 Lampholder for Testing Contact Making

The drawing is intended only to illustrate the essential dimensions of the gauge.

(1) The thread of the gauge is made to comply with the maximum dimensions of the appropriate cap, 

illustrated on sheet 7004-23, subject to a tolerance of +0.0 -0.03.

When the switch is in position 1 and the gauge is screwed home in the holder, the indicator lamps 

shall light.

In case of doubt whether the gauge is fully screwed home, a feeler gauge with an approximate thick-

the top of the lampholder.

the following lamps when these are fitted with E14 caps, in accordance with sheet 7004-23:
