Texas Home Inspector Standards of Practice
THE FOLLOWING STANDARDS OF PRACTICE HAVE BEEN ESTABLISHED BY THE STATE OF TEXAS AND THE TEXAS REAL ESTATE COMMISSION FOR INSPECTORS LICENSED IN TEXAS
§535.230. Standards of Practice: Inspection Guidelines for Electrical Systems.
(a) Service entrance and panels. The inspector shall do the following:
....(1) observe service entrance cables for integrity of insulation, drip loop, separation of conductors at weatherheads and clearances;
....(2) observe that the drop, weatherhead and mast are securely fastened;
....(3) inspect for the presence of a grounding electrode conductor in the service where visible, secure connection to the grounding electrode or grounding system;
....(4) inspect all accessible main and subpanels to ensure they are secured to the structure and appropriate for their location (weather-tight if exposed to weather, appropriate clearances and accessibility), with inside covers (dead fronts) in place , the conductors are protected from the edges of metal panel boxes, trip ties are installed on labeled 240 volt circuits, fasteners are proper and knock-outs filled ;
....(5) inspect the condition of the wiring in the panels, its type (for example, copper or aluminum) and the compatibility of overcurrent protectors for the size of conductor being used and for proper sizing of listed equipment of overcurrent protection and conductors, when power requirements for listed equipment are readily available and conductors are properly identified (such as neutrals marked when used as hot conductors);
....(6) observe when the panel is installed in a hazardous location, such as a clothes closet);
....(7) report the presence or absence of appropriate connections, such as copper/aluminum approved devices, pig-tailed connections or crimp connections; and
....(8) observe the presence of main disconnect(s).
(b) Specific limitations for service entrance and panels. The inspector is not required to do the following:
....(1) determine service capacity amperage or voltage or the capacity of the electrical system relative to present or future use;
....(2) determine the insurability of the property; or
....(3) conduct voltage drop calculations;
(c) Branch circuits, connected devices and fixtures. The inspector shall do the following:
....(1) inspect all accessible receptacles to determine whether:
........(A) power is present;
........(B) polarity is correct;
........(C) the unit is grounded, if applicable;
........(D) there is evidence of arcing or excessive heat;
........(E) the unit is secured to the wall;
........(F) the cover is in place; and
........(G) ground fault circuit interrupter devices are properly installed as set forth by the current edition of the National Electric Code, publication 70A of the National Fire Protection Association and operate properly as shown by use of a tester (absence, improper installation, or improper operation of devices shall be reported as an existing or recognized hazard).
....(2) operate all accessible wall and appliance switches to determine if:
........(A) they are operational;
........(B) there is evidence of arcing or excessive heat; and
........(C) they are fastened securely with covers in place.
....(3) inspect installed fixtures including lighting devices and ceiling fans;
....(4) report inoperable or missing fixtures;
....(5) observe and report deficiencies of exposed wiring, wiring terminations, junctions and junction boxes;
....(6) observe and report deficiencies or absences of conduit in appropriate locations and for secure termination of conduit;
....(7) inspect appliances and electrical gutters for proper bonding;
....(8) observe subpanels for bonding and grounding;
....(9) inspect for presence of disconnects in appropriate locations;
....(10) inspect (if branch circuit aluminum wiring is discovered in the main or subpanels) a random sampling of accessible receptacles and switches and report the presence or absence of appropriate connections, such as copper/aluminum approved devices, pig-tailed connections or crimp connections;
....(11) inspect for the improper use of extension cords;
....(12) report if the inspector is unable to verify grounding of 240 volt appliances or plumbing or gas distribution systems; and
....(13) inspect for inappropriate parallel wiring, such as to electric furnaces.
(d) Specific limitations for branch circuits, connected devices and fixtures. There are no specific limitations for branch circuits, connected devices and fixtures.
