PANEL COVER - Residential Electrical Panel Cover Inspection and Special Safety Hazards - Look before you touch!
Information in this electrical inspection article series was presented by Daniel Friedman - InspectApedia.com, and discussed by the Hudson Valley chapter of the American Society of Home Inspectors - HVASHI Seminar 12 Sept 2002, Updated April 2006, April 2009.
Readers of this article should also be sure to review Safety Hazards and Safe Electrical Inspection Procedures for Inspectors examining Residential Electrical Systems and should pay special attention to the following chapters from that article: ELECTRICAL PANEL INSPECTION SAFETY - Removing Electric Panel Covers - Electrical Panel Cover Screws - Electrical Panel Interior Hazards - Testing Main Breakers or Fuses and Inspect Breakers, Fuses. Carson Dunlop's sketch at page top shows where the electrical inspection starts at a residential property.
Before Touching or Opening the Electrical Panel for Inspection
CIRCUIT WIRING AMPS FUSING - Electrical branch circuit wiring amps/fusing defects - Copper electrical wiring
Match wiring gauge to ampacity - the following describe copper wire sized or gauges and the matching circuit ampacity or overcurrent protection that is required to be provided by fuse or circuit breaker:
Exceptions to these wire sizes and fusing occur for special circumstances such as air conditioners whose motors produce a brief current surge during startup.
MAIN DISCONNECT INSPECTION - Electrical Panel Main Disconnect Inspection - Do you Pull the Main Fuse or Test the Main Breaker?
