ATTENTION: Susan Lehmann

Dear Susan, REFERENCE: NPS Arc Flash Evaluation - KLGO Trip Report

On 05/20/24 through 05/22/24 Jason Gold, with Consolidated Contracting & Engineering, and Connor Zietlow with RSA Engineering travelled to Skagway to investigate the electrical distribution systems. The intent of the site visits were to gather enough information on the equipment to provide an accurate arc flash calculation, provide warning labels for the equipment, and determine any code deficiencies. Any equipment which is single phase and 240V, or less, an arc flash calculation is not required. See one-line diagrams for further information on site electrical systems. The following report will address any code issues awe discovered as part of our investigation.

General:

In existing installations where receptacles are being replaced, per NEC 406.4(D), new receptacles are required to conform with the most recent adoption of the NEC. Example: All housing unit receptacles replaced are required to be UL tamper-resistant type and have AFCI protection, and all receptacles replaced in areas of assembly, per NEC 518, are required to be UL tamper-resistant type.

Maintenance Shop:

The Maintenance Shop electrical system starts with (3)15KVA pole-mounted transformers feeding underground to an exterior building mounted current transformer (CT) cabinet in use as a pull box, with a remote meterbase (Image #1) located adjacent. From the CT, the secondary service laterals route inside to a 120/208V, 600A, 3Ø, 4W Square D type QED switchboard a 600A main circuit breaker with a shunt trip accessory which functions as a CT and building disconnect, denoted as ’CT Main Breaker’. The shunt trip breaker in ‘CT Main Breaker’ has an exterior keyed switch (Image #2) utilized as the exterior building disconnecting means.

’CT Main Breaker’ feeds a 120/208V, 600A, 3Ø, 4W Square D type I-line main lugs only distribution panel denoted as panel ‘MDP’ (Image #3) located directly adjacent. Panel ‘MDP’ feeds (3) 120/208:120/240V, 3 KVA, 1Ø dry type(buck-boost) transformers (Image #4), and (4) 120/208V, 225A, 3Ø, 4W Square D type NQOD panelboards with main lugs only denoted as Panels ‘B’ (Image #6), ‘C’ (Image #7), ‘D’ (Image #8), and ‘M’ (Image #9). The (3) dry-type transformers are fed via a 250A 3-Pole circuit breaker, and the four panels ‘B’, ‘C’, ‘D’, and ‘M’ are fed via 100A 3-Pole circuit breakers.

The (3) 120/208:120/240V, 3 KVA, 1Ø dry type transformers work in parallel to provide a voltage boost to the 120/208V, 3Ø system to provide 130/230V, 3Ø power to panel ‘A’ (Image #5), a Square D 225A, 240V, 3Ø, 4W type NQOD panel with 225A 3-Pole main circuit breaker and a nominal voltage of 130/230V. The intent of boosting the voltage is to provide power to equipment that is rated for 230V so that it preforms closer to its potential maximum output.

15. Panel ‘B’ and ‘M’ circuit directories appears to be out of date. Trace out existing circuits in panels and provide clear, evident, and distinguishable typed circuit directories for each in accordance with NEC 408.4.

Electrical Recommendations

1. Data outlet is missing cover plate. Recommend providing cover plate to protect wire integrity.

2. Fuel alarm is non-functional. Recommend further investigation into the cause of failure, and appropriate measures taken to restore system functionality.

3. Panel ‘B’, ‘C’, ‘D’ and ‘M’ have neutrals that are shared between circuits. Note that this may have not been a code requirement when the equipment was installed and therefore could be “grandfathered” but does not meet the current NEC minimum requirements. Recommend that all circuits with shared neutral are handle-tied together or provided with dedicated neutrals.

4. Panel ‘B’ circuits 32-38 have poorly landed conductors. Recommend de-energizing circuits and re-landing conductors.

Panel ‘A’ circuit #10 disconnect enclosure and table saw disconnect are grounded via the metallic raceway per NEC 250.118. Due to seismic activity, we recommend providing a dedicated bare or green insulated conductor as the equipment grounding conductor.

Maintenance Garage:

The Maintenance Garage electrical system starts with (3)15KVA pole-mounted transformers feeding down to an exterior pole-mounted combination meterbase disconnect (CMD) (Image #11) with 120/240V, 100A 2-Pole service disconnect. The CMD feeds down into a pole-mounted 120/240V, 125A, 1Ø, 3W Square D type QO load center with main lugs, denoted panel ‘Ext’ (Image #12). Panel ‘Ext’ routes into the garage to feed a 120/240V, 100A, 3Ø, 3W Square D type QO load center with 200A 3-Pole main circuit breaker denoted as Panel ‘Garage’, via a 100A, 2-pole breaker. Panel ‘Garage’ feeds an exterior Square D 200A fused disconnect used as a pull box via a 20A 2-Pole breaker. From the pull box cable is fed to an interior 120/240V, 100A, 1Ø, 3W ITE load center with 100A 2-Pole main circuit breaker denoted as Panel ‘Cold Storage’.

Code Deficiencies

5. KO is missing from Panel ‘Ext’ feeding garage door opener. Provide KO for unused openings per NEC 110.12(A).

6. Panel ‘Ext has double landing neutrals. Double landing conductors is not an approved means of installation in accordance with instructions for equipment and is not allowable per NEC 110.3(B) unless equipment is listed. Remove load side neutral wire from double landed lug and use spare lug to bond to neutral bar.

7. Panel ‘Ext’ has no equipment grounding conductors feeding receptacles. This is not a code violation assuming receptacles are properly bonded to conduit via grounding terminal bonding jumper or the receptacle has direct metal-to-metal contact with the backbox per NEC

250.146. Due to the age and condition of the equipment, we find this unlikely. Ensure that receptacles are properly bonded to conduit. If not, either properly bond to conduit per NEC

250.146 or provide equipment grounding conductors per NEC 250.64 to establish an effective path to ground per 250.4(3).

8. Conductors from CMD to Panel ‘Ext’ are undersized for existing overcurrent protection device. Replace #4 AWG conductors with #2 AWG conductors that are properly sized for 100A 2-Pole breaker per NEC 310.16.

9. Panel ‘Ext’ does not have panel schedule. Trace out circuit in panel and provide clear, evident, and distinguishable typed circuit directories for panelboard per NEC 408.4.

10. Panel ‘Garage’ is a 3Ø panel fed with (2) conductors, with jumper connecting phase A to phase C. Ensure bus lugs are rated for number/size of conductors terminating on them, and that no two circuits on the (2) A phase busses are wired to share the same neutral.

11. Panel ‘Cold Storage’ enclosure is not bonded to ground. Bond enclosure to establish an effective path to ground per NEC 250.110.

12. Conductors from Panel ‘Garage’ to Panel ‘Cold Storage’ are undersized for existing circuit breaker. Replace #10 conductors with #2 conductors that are properly sized for 100A 2-Pole breaker per NEC 310.16.

1. Receptacle below Panel ‘Ext’ has one outlet not functioning. Recommend replacing with new weatherproof wet rated receptacle with “While In Use” cover.

2. Panel ‘Ext’ has neutrals that are shared between circuits, with no handle-ties. Note that this may have not been a code requirement when the equipment was installed and therefore could be “grandfathered” but does not meet the current NEC minimum requirements.

Recommend that all circuits with shared neutrals are handle-tied together or dedicated neutrals installed.

3. Panel ‘Ext’ is in poor condition and is beginning to rust. Recommend replacing with new NEMA 3R panelboard with similar bus and voltage ratings.

While they may not be required due to the size and occupancy of the building, recommend repairing or replacing non-functioning emergency lights with new LED in existing locations.

10. Panel ‘Garage’ is grounded per 250.118 with the use of metallic raceway. Due to seismic activity, we recommend providing a dedicated bare or green insulated conductor as the equipment grounding conductor.

Curatorial Storage:

The Curatorial Storage electrical system starts with (3)15KVA pole-mounted transformers feeding down to an exterior pole-mounted combination meterbase disconnect (CMD). Due to insufficient access, we assume that the CMD is a 120/240V, 200A Midwest CMD with a 2-Pole service disconnect. The CMD routes inside to feed a 120/240V, 225A, 1Ø, 3W Square D type NQOD panelboard denoted Panel ‘CS’ (Image #15).

Code Deficiencies

1. No code deficiencies were observed for this system.

Electrical Recommendations

1. CMD is beginning to rust. Recommend replacing with new equipment with similar bus and voltage ratings.
