Deficiency Description Required Repair

Meterbase is missing a KO. Provide KO.

Panel 'B' has the equipment grounding conductor terminated on the Neutral bus.

Install ground bar in existing panel 'B' and move ground wires off of neutral bar and over, Panel 'B' is fed using #2 AWG copper conductors, rated for 95A, but is protected by a 125A breaker which is too large to protect the conductors.

Replace 125A breaker with a new 100A breaker rated for use in the existing panel.

Weight room building requires a disconnect per NEC 225.31.

Intercept incoming feeders to Panel 'W' and install overcurrent protection device such as a breaker or fused disconnect.

Panel 'W' has its equipment grounding conductor landed on the neutral bus bar, and the incoming feeders are labeled incorrectly.

Neutral wire needs to be moved off the phase lug and onto the neutral bar and the equipment grounding conductor needs to be removed from the neutral bars and on the ground bar.

Feeders to Uniform Cache Panel are exposed without protection.

Provide conduit or other approved means of preotection to exposed feeders. .

Panel ‘C’ is of unknown manufacturer type and is missing several knockouts and wire clamps.

Replace Panel 'C' with more readily available panel type and/or provide KO seals and wire clamps as required.

Panel ‘A’ is a Siemens type EQ load center and has several Thomas & Betts type TB breakers.

If work is done on these circuits the breakers will need to be replaced with breakers listed with the Siemens type load center.

Panel 'A' has neutral and ground bonded together

Install dedicated ground bar in panel. Move all ground wires to this dedicated bus bar.

Panel 'B' has neutral and ground bonded together

Install dedicated ground bar in panel. Move all ground wires to this dedicated bus bar.

Panel 'C' has neutral and ground bonded together

Install dedicated ground bar in panel. Move all ground wires to this dedicated bus bar.

Panel 'D' has neutral and ground bonded together

Install dedicated ground bar in panel. Move all ground wires to this dedicated bus bar.

Panel 'M' has neutral and ground bonded together

Install dedicated ground bar in panel. Move all ground wires to this dedicated bus bar.

Panel 'C' Is a Thomas & Betts type TBL

Panel which is no longer manufactured and breakers installed are not listed for use in this panel.

If any upgrades are required, the entire panel will need to be replaced.

Battery Shed has no grounding electrode or disconnect.

Install 60A disconnect in place of feeder LB on the exterior of the building.

Panel 'BA' has no grounding bus bar.

Install ground bar in existing panel 'BA' and move ground wires off of neutral bar and over, In Panel 'A' ground and neutral wires terminated on Neutral bar. No ground bar installed.

Provide dedicated ground bar in panel and move ground wires from neutral to ground bar.

Panel ‘V’ is missing several KOs and a deadfront.

Replace with a new panel with the ratings and model information available.

Electrical distribution system equipment backboard was hit by a vehicle. The supports and electrical installations were damaged.

While the wiring is still intact, the support system and all raceway systems need to be replaced.

Panel 'F' has no grounding bus bar.

Since the panel is no longer manufactured and supports are damaged, replace panel with similar Siemens or Square D product.

Panel ‘A’ EGCs need to be moved to the existing ground bar. Panel ‘A’ is no longer manufactured. Conductors are not color identified by phase or are mis-labeled.

Move panel ‘A’ EGCs to the existing ground bar. Relabel the feeders with A-phase as black, and B-phase as red.

Panel ‘B’ EGCs need to be moved to a new ground bar. Conductors are not color identified by phase or are mis-labeled.

Move panel ‘B’ EGCs to a new ground bar.

Relabel the feeders with A-phase as black, and B-phase as red.

Panel ‘C’ EGCs need to be moved to the existing ground bar. Conductors are not color identified by phase or are mis-labeled.

Move panel ‘C’ EGCs to the existing ground bar. Relabel the feeders with A-phase as black, and B-phase as red.

Panel ‘S2’ EGCs need to be moved to a new ground bar. Did not see evidence of a grounding electrode to a ground rod. Feeders to Panel 'S2' require disconnect per NEC

225.31.

Investigate this further and install as required. Install disconnects on the Feeders to Panel 'S2' per NEC 225.31.

Panel ‘S1’ EGCs need to be moved to a new ground bar. Did not see evidence of a grounding electrode to a ground rod. Feeders to Panel 'S1' require disconnect per NEC

225.31.

Investigate this further and install as required. Install disconnects on the Feeders to Panel 'S1' per NEC 225.31.

Feeders to Panels ‘S1’ and ‘S2’ require disconnects per NEC 225.31.

'S1' and 'S2' per NEC 225.31.

In Panel 'S' has a NEMA 1 rated enclosure, the ground and neutral wires are terminated on Neutral bar, no ground bar is installed, KO seals are missing, and the panel is not properly mounted to a structure.

Provide NEMA 3R enclosure for panel, provide a dedicated ground bar in panel and move ground wires from neutral to ground bar, and properly mount to a structure.

Panel 'S' is Provided with a NEMA 1 enclosure which is not rated for use in exterior locations.

Feeder for Mini trailer/building is an extension cord not rated for direct burial and should not be used as such a permanent basis.

Replace extension cord with a more permanent feed to a twist-lock receptacle mounted on a pedestal. Then replace the existing receptacle with a 10’-15’ section of extension cord with a plug. The cord can be coiled on a building-mounted hook when not in use. At this time the proper 4-wire connection can be installed to Panel ‘M’ and

Panel ‘F’ missing grounding bar.

Provide new grounding bar in Panel 'F'.

Move panel ‘F’ EGC and grounds to the new grounding bar.

The 20A, 1-pole breaker may be feeding 2-pole motor loads. We did not pull submersible fuel pumps to verify.

If they are 2-pole motors then the existing breakers need a handle tie or need to be replaced with appropriate 2-pole breakers.
