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.
Purpose of ISI  Periodic examination to detect degradation â âThe intent of the Code is to provide for, on a case by case basis, a review of the indications that show potential signs of distress and relate the condition to the service requirements to which the component is subjected.
