Changing Load Side Lugs on Disconnect

[MBCampbell]

I have a situation where the load side lugs are too large for the load side wires. The disconnect has removable lugs and states if the main lugs are changed, or if compression lugs are installed, toque to 100 inch lbs. This to me would suggest the ability to change to a compression lug.

There is not a lug that will accommodate the size wire in the accessories list.

How does UL view this? How does the NEC view this?

Field Modifications
What happens to the Listing if a UL-Listed product is modified in the field?​

An authorized use of the UL Mark is the manufacturer?s declaration that the product was originally
manufactured in accordance with the applicable requirements when it was shipped from the factory. When
a UL-Listed product is modified after it leaves the factory, UL has no way to determine if the product
continues to comply with the safety requirements used to certify the product without investigating the
modified product. UL can neither indicate that such modifications ??void?? the UL Mark, nor that the
product continues to meet UL?s safety requirements, unless the field modifications have been specifically
investigated by UL. It is the responsibility of the Authority Having Jurisdiction (AHJ) to determine the
acceptability of the modification or if the modifications are significant enough to require one of UL?s Field
Engineering Services staff members to evaluate the modified product. UL can assist the AHJ in making this
determination.
An exception for a field modification authorized by UL is when the product has specific replacement
markings. For example, a switchboard may have specific grounding kits added in the field. The
switchboard is marked with a list of specific kit numbers that have been investigated for use in that
particular switchboard. Only grounding kits that are included on the marking on the product have been
investigated for use in that product.
If a party wishes UL to determine if the modifications made to a UL Listed product comply with UL
requirements, the appropriate Field Engineering Service can be initiated to investigate the modifications.
This investigation will only be conducted after UL consults with the AHJ to ensure that UL?s investigation
addresses all areas of concern and meets all of the AHJ?s needs.
If you have any questions or would like to inquire about a Field Evaluation, contact Field Services at
+1-877-UL-HELPS, prompt #2 (+1-877-854-3577) or visit http://www.ul.com/field/index.html.

If the list of lugs on the label do not correspond to the lug size you will need, I suggest using a pin to match the lugs on the label.

if you can't find the right size pin adapter, just install oversize wire and bug down in the can.

I assume that the lugs on the list of accessories are mechanical lugs. Based on the statement from the instructions, I would have no problem with the installation of a compression lug that matches the wire size, assuming that the hole in the lug matches the bolt on the disconnect.
