NM type wire should be protected when potential physical damage is present. (NM cable is not approved for surface installation without protection).

Junction box A4 on the Electrical room wall has open splices, a missing box cover, and an unterminated wire.

NM type wire should be protected when potential physical damage is present. (NM cable is not approved for surface installation without protection).

Device A1 is a Pilot Switch controlling the overhead lights.  Wires above the switch are not secured in an approved method (more than one cable under a staple and unsecured cable further above).  Nonmetallic-sheathed cable shall be supported and secured by staples, cable ties, straps, hangars, or similar fittings designed and installed so as not to damage the cable, at intervals not exceeding 1.4m (4 1/2 ft) and within 300mm (12in.) of every outlet box, junction box, cabinet, or fitting.

Receptacle A2 has no hot wire (black) connection and the attachment screw on the receptacle shows signs of being overheated and burnt.

Receptacle A3 has reverse Polarity (Hot wire (black) reversed with the neutral wire (white).

Receptacle A4 has the Neutral wire (white) reversed with the ground wire (bare).

Receptacle B1 is an ungrounded type receptacle.

Reverse polarity, hot wire (black) is reversed with the neutral wire (white).  Also missing device cover.

Reverse Polarity, Ground wire (bare) is reversed with the Hot wire (black).

Open Neutral, white wire is disconnected from the terminal screw.

Open neutral on the bottom receptacle, the brass tab that connects the top and bottom receptacle on the neutral side is broken.

Open Ground, the Ground wire (bare) has been disconnected.

The top Receptacle is not energized, the brass tab that connects the top and bottom receptacle on the hot side is broken.

Receptacle is not energized, the hot wire (black) is disconnected.

Wires above the switch are not secured in an approved method (more than one cable under a staple).  The switch controls the overhead light (Light does not come on during switch operation).

GFCI receptacle does not trip when tested.

Main feeder wires are undersized (must be sized according to the main breaker amperage rating of 200 Amp).  Main feeder wires missing Anti/Oxidant paste.  Feeder wire insulation stripped to far (recommend maximum of ¼” of conductor exposed above the lug).  Conductor wires have been trimmed reducing the currant carrying capacity of the feeder.  Splices in the panel.  Missing NM cable connector in the bottom of the panel.  Arch fault breaker missing neutral conductor.  Broken 20 Amp breaker.  Loose double tap breaker.  Sub Panel feeder (threaded offset nipple) is missing bonding bushing and ground bonding jumper wire.

Bonding at Services
NEC Section 250.92(B) is applicable to
(Bonding at services), and in part states,
“Bonding jumpers meeting the other
Requirements of this article [Article 250] shall
be used around concentric or eccentric
knockouts that are punched or otherwise
formed so as to impair the electrical
connection to ground.” For services, this
confirms that (bonding jumpers) are required
unless all concentric or eccentric knockouts
have been removed.

Undersized feeder wire.  No grounding conductor.  No isolated grounding bar.  No insulated bushing on the threaded offset nipple.

Main feeder wires are undersized (must be sized according to the main breaker amperage rating of 200 Amp).  Main feeder wires missing Anti /Oxidant paste.  Feeder wire insulation stripped to far (recommend maximum of ¼” of conductor exposed above the lug).  Conductor wires have been trimmed or damaged reducing the currant carrying capacity of the feeder.  Sub Panel feeder (threaded offset nipple) is missing bonding bushing and ground bonding jumper wire.

Rain Tight type rated for outdoor use.  Feeder wire is undersized for the 200A main breaker.  Bonding bushing is missing on the threaded offset nipple.  Threaded offset nipple is missing bonding bushing and ground bonding jumper wire.  Open or unused breaker slots should be covered.

Rain Tight type rated for outdoor use.  Feeder wire is undersized for the 125A main breaker. Missing the correct ground termination bar.  Missing inner dead front cover.

Federal Pacific Circuit breaker Panels (FPE):

Federal Pacific Electric "Stab-Lok® " service panels and breakers are a latent hazard and FPE circuit breakers can fail to trip in response to overcurrent, leading to electrical fires. The breakers may also fail to shut off internally even if the toggle is switched to "off." Some double-pole (240-Volt) FPE circuit breakers and single-pole FPE Stab-Lok® circuit breakers simply do not work safely. (The problem lies in the dissimilar materials copper to aluminum alloy used between the breaker attachment point and the main buss).

Zinsco Sylvania/Zinsco Circuit breaker panels:

While a Zinsco panel can function properly for years and even decades, as higher energy demands are placed upon a Zinsco panel they have a strong tendency to overheat. When this happens, breakers melt and are no longer capable of tripping. This leads to an extreme amount of energy surging that can’t be shut off manually, and there is a great potential for these panels to catch fire. If you have a Zinsco electrical panel It is recommended that a review by a licensed Electrical contractor be done. (The problem lies in the dissimilar materials used between the breaker attachment point and the main buss).
