GFCI Issues

[TVH]

1) How often should a GFCI be tested?
2) Are GFCI required to be accessible for testing (ie. GFCI enclosed in a locked Dibribution Panel Board)?
3) Is the GFCI test button just a mechancial trip test or does the test actually cause a ground fault?

Appreciate.

1. Every 30 days

2. Yes, in 2011 NEC readily accessible.

3. The test button is not a mechanical trip, it tests the device.
