Yes it will void the item's listing. You would need to use a drain fitting.
Again, that is an opinion, not a statement of fact.

UL does not know what the effect of a modification may have on the safety of the product or the continued validity of the UL certification mark
Is not possible to tell from picture ....but there may be a self sealing locknut inside of body?
So even if drilling the side of the L.B. was part of the listing and an intended application ,... How now do we connect the conduit to these holes ???
Huh?......
Sealing Locknuts ? Sealing locknuts are intended for use with threaded rigid metal conduit and intermediate metal conduit with one sealing locknut in the outside or the inside and either an ordinary locknut or sealing locknut on the opposite side of the enclosure for wet locations or liquid-tight applications. Sealing locknuts may also be used with Listed wet location or liquid-tight fittings where so marked on the fitting carton.
1.17 Externally-threaded adapters (also referred to as terminal adapters) covered by these requirements are fittings intended for joining a length of rigid PVC conduit or elbow or other bend to:
a) The knockout area of a metal box with a metal locknut,
b) A threaded metal hub or fitting on a metal box,
c) A threaded hub on a phenolic box, or
d) A knockout in a phenolic box.
To elaborate a bit, even UL does not say a modification voids the listing.
They say that a modification makes it imposable for them to say the unit meets the standards.
By your interpretation I could not replace a damaged cord cap with a correctly rated new one.
Some commonsense must be exercised. :smile:
What is a drain fitting?
I typically "arrange to drain" by installin a conduit body at the lowest point. I presume that it need not drain continuously, but must have a means to easily remove water.
What do you think is required, 24/7 drainage? Best method, sure. Mandatory?
It was also proablly shipped in a box but I can remove that as well.
I have been working with UL listed boxes like this
for a long time and I have never seen any instructions that say I may add any holes to it.
7.7 Conduit hubs, closure plates, and other equipment
7.7.1 Enclosures intended for use with conduit hubs, closure plates, and other equipment (such as push-button switches) intended to be field installed shall be marked or provided with instructions that identify the equipment necessary to maintain the environmental integrity of the enclosure. This may be accomplished by identifying the necessary environmental type designation or by identifying the specific
manufacturer and model number of the field installed equipment.
According to UL 50, in which these enclosures are typically listed to:
If you don't receive any type of instruction in the box or label , then, technically, the manufacturer is violating the requirement of the UL listing.
... then there is no listing for it's current condition.
Actually once something has been installed UL must take a "hands-off" approach as they have not tested the exact actual installation/condition.
As UL states - their mark indicates the product/device was manufactured correctly, and it met the applicable standards when it left the factory. After that point it is up to the AHJ to make sure are acceptable.
