Phase Inspection. 1  Inspect the electrical system as a whole including outlets, GFCI & AFCI protection, switches, fixtures, panels, circuit breakers & disconnects. 2  Inspect the plumbing for any visible leaks, drips, water supply, proper venting of the drains and waste lines.
This test takes between 10 to 20 minutes andis more comprehensive than the phase oneprocedure since all the components in the system are evaluated. Evaporative leak detection using a smoke machine, visual inspection, including phase one, phase two and the use of a scan tool for verifying...
