Question:
$ z& e: I$ C; t* U# n( t5 hSome lampholders intended to be built into appliance are of such construction (see the photos below) that
it is impossible to test them by use of some gauges, e.g. a gauge according to the standard sheets 7006-30
and 7006-31, and according to Figure 11, if a lampholder is not re-assembled prior to test. This means that

the re-assembled lampholder, the test probe easily reaches a contact. However, in real situation, a contact
