I'm building a house and am working on installing in the electrical. I have a large deck with lots of led lighting and want to hardwire the low voltage transformer to a gfci circuit breaker. All the low voltage transformers I see online have a cord with a three prong plug. Is there's a line of transformers that are made to be hardwired into the house? Failing that, is it acceptable to replace the plug wire with Romex inside the wall? I'm guessing it's not.

Any info or suggestions would be appreciated.

Builder contractor. I have a technical background in electricity and electronics and a degree in aerospace engineering. Among other things, I worked as a system engineer for the navy overseeing the custom installation of weapon systems on a test ship. I dealt with everything from electrical wiring to ventilation to plumbing. I wired my last house from the weathehead to the outlets with no hits from the inspector. I removed a load bearing wall and supported the existing ceiling/trusses with a concealed beam in the ceiling. I also plumbed the house with copper from the meter throughout the house. I calculated the runs and re-plumbed the house for natural gas as well, ensuring all outlets had adequate flow. I drew all my own plans for the remodel and pulled permits for everything. I'm facile enough in most building trades though I'm far from being a contractor. But I'm quite confident in my ability to wire things correctly. I just need to know what's acceptable.

Cut the male end off of a GFCI three way cord, wire it to you panel box? pull trough conduit(s)
Yeah, that doesn't sound right...

Really I'm just looking to source a 300 watt LED transformer made to be hardwired to a breaker. I figured in a forum about outdoor lighting someone would know if they're even out there. Short of that, a legitimate way to convert a corded transformer to hardwired, if that's even possible. Im not looking to get crazy.

I fail to understand the need for hardwiring;
Your need to understand being irrelevant notwithstanding, in addition to the deck lighting I want to run LED lights on the outside walls of my house running the wires in the exterior walls while mounting the transformer on an interior wall in a convenient closet. Hardwiring the unit makes for a cleaner installation while allowing me control the exterior and deck lighting from inside the house.

However, the only hardwired units I've seen online are simple transformers not intended for wall mounting. I thought maybe someone in this forum might be able to provide some practical insight on brands and models that I might consider.
Modifying a corded transformer would invalidate its UL certification. With your background, you should know that.
Please give me a little credit. I've been implying all along it's probably not legit. ATST, I saw one unit that appeared to have an optional cord although it was otherwise unsuitable. Not sure why the cord was optional but it is one reason I"m asking supposed (Cut the plug off and wire it directly to the panel? Please.) professionals for their opinion. Thank you for yours.
