Significant Reportable Defect

Pursuant to the FL HI Statute at 468.8323 an inspector, in his professional opinion, reports significant defects with components. Is it is significant defect if an electrical system is not grounded? Should this be reported?

Be more specific. Are we talking a circuit or three, or the ENTIRE system, panel and all???

Yes I believe it is whether it be the entire system or one receptacle. Most appliances require a ground now a days.

That is not an accurate statement in the U.S.

Here is the Florida SOP on electrical.

61-30.803 Standards of Practice, Electrical Systems.
(1) Electrical systems and components include the following:
(a) Service entrance conductors, drip loop, cables, and raceways;
(b) Main service equipment and main disconnects;
© Service grounding;
(d) Interior components of main service panels and sub panels;
(e) Conductors;
(f) Over current protection devices;
(g) Readily accessible installed lighting fixtures, switches, and receptacles;
(h) Ground fault circuit interrupters;
(i) Amperage and voltage rating of electrical service;
(j) Main disconnect(s);
(k) Methods or types of wiring;
(l) Smoke detectors;
(m) Carbon monoxide detectors;
(n) Arc fault circuit interrupters.
(2) The inspector shall inspect all of the visible and readily accessible electrical systems and components.
(3) The inspector is not required to inspect:
(a) Remote control devices;
(b) Security alarm systems and components;
© Low voltage wiring, systems and components, ancillary wiring and systems and components not a part of the primary electrical power distribution system;
(d) Generators, photovoltaic solar collectors or battery or electrical storage devices and associated equipment.
(4) The inspector is not required to:
(a) Measure amperage, voltage or impedance;
(b) Perform a load calculation;
© Insert any tool, probe, or device into any electrical component;
(d) Determine the accuracy of circuit labeling.

All circuits on the primary electrical system in a residence requires a ground,
Service and equipment.

Grounding. It is best that all circuits be grounded to the panel board, but this was not required by the National Electrical Code prior to 1965. Do not assume that circuits in metal cable are grounded without testing each outlet. Also, do not assume that three-prong plug convenience outlets are connected to ground. Remove each one to observe the presence of a connected ground wire. Check to see whether GFI (ground fault interruption) type receptacles have been installed in laundries, kitchens, and bathrooms, and test their operation. These types of receptacles were not required before 1990, but are easily installed as replacements.
