Precision Hardware Inc (PHI) EPT-12C Electric Power Transfer, 12 CEPT-12Conductor, Quick Connect

Yes. The EPT-12C accommodates a 180 degree door swing, and it's non-handed, so the same unit goes on a left hand or right hand opening without ordering a specific version. The wire is protected by a stainless steel spring conduit between the frame and the door leaf, which is what lets it flex through the full arc.

The EPT-12C is UL Listed and carries UL10C, which is the positive pressure fire door test standard. That's the listing an inspector looks for when a power transfer is cut into a labeled opening.

Twelve conductors total: 10 at 24 gauge and 2 at 18 gauge. The two 18 gauge legs are the heavier pair, which is what you use for the current-carrying load, and the ten 24 gauge conductors cover signal and monitoring runs such as request-to-exit, latch monitor, and door position. Twelve terminations is enough to serve an electrified device and its monitoring switches through a single transfer rather than cutting in two.

No. The EPT-12C is non-handed, so one part number covers both leaves of a pair and any handing on a single door. Order two of the same unit for a pair where both leaves are electrified.

The closest one-for-one match is the Precision Power Transfer, 12 Conductor, Quick Connect (PHI-EPT-12C), which is the same 12 conductor quick connect power transfer in the EPT Series. The BEST EPT-12C carries a pre-installed twelve wire harness with 10 wires at 24 gauge and 2 at 18 gauge, is non-handed, accommodates 180 degree swing, and is UL Listed to UL10C, so a swap keeps the same conductor count and the same quick connect terminations you would already be wiring to.

The Securitron CEPT Concealed Electrical Power Transfer (SEC-CEPT) is the concealed option in the CEPT Series and is fire rated. The EPT-12C is a surface-visible transfer with a stainless steel housing and spring conduit carrying its twelve wires between frame and door, so where the specification calls for the wiring path to disappear into the prep entirely, the CEPT is the one built for that.

They solve the same problem in different ways. The Securitron TSB-C is a durable and tamper resistant door cord in the TSB-C Series - an exposed armored loop that runs across the hinge gap. The EPT-12C is a mortised transfer with a stainless steel housing and spring conduit and pre-installed quick connect plugs, carrying twelve wire terminations and accommodating a 180 degree swing. A door cord will not give you the twelve conductor quick connect harness or the mortised appearance, so it is a substitute only where an exposed loop is acceptable.

The Securitron CEPT (SEC-CEPT) carries a fire rating. The BEST EPT-12C is UL Listed to UL10C, the positive pressure fire test standard for door assemblies. Either can be specified where the opening is rated; the CEPT does it concealed, while the EPT-12C brings the twelve conductor quick connect harness in a stainless steel housing.

It ships with the twelve wire harness pre-installed and quick connect plugs already fitted on it. You're plugging into the device and the frame side rather than stripping and splicing twelve conductors in the field, which is the difference between a short install and an afternoon in a frame cavity.

A power transfer such as the EPT-12C mortises into the door edge and frame so the wire run is concealed and protected inside a stainless steel housing, and it takes 12 conductors. A surface door cord, like the Securitron TSB-C, mounts on the face of the opening instead: no frame and door edge prep, but the loop is exposed. Concealed transfer for a finished or higher-traffic commercial opening; door cord when you cannot cut the door and frame.

Securitron makes several. The EPT is their heavy duty electrical power transfer, the SEPT is the square-cut version of it, also heavy duty, and the CEPT is a concealed transfer that carries a fire rating. The Securitron TSB-C is the surface door cord option rather than a mortised transfer. What the EPT-12C brings against them is a specific conductor count, 12, with the harness and quick connect plugs already installed.

Both Securitron units are heavy duty transfers: the Securitron EPT (SEC-EPT) in the EPT Series and the Securitron SEPT (SEC-SEPT) in the SEPT Series, which is square-cut. The square-cut body of the SEPT suits a frame and door prep routed with square corners, while the EPT follows the round-end profile. The BEST EPT-12C differs from both in what it ships wired: a pre-installed twelve wire harness of 10 wires at 24 gauge and 2 at 18 gauge with quick connect plugs already terminated.

The twelve conductor count on the BEST EPT-12C is sized for openings running an electrified lock, a request-to-exit switch, and door position monitoring together. Where the run is simpler, the Securitron EPT (SEC-EPT) and the square-cut Securitron SEPT (SEC-SEPT) are both heavy duty transfers that handle the same hinge-side crossing, and the Securitron TSB-C door cord (SEC-TSB-C) covers openings where a surface run is acceptable.

Commercial. The EPT-12C is built for commercial openings, with a stainless steel housing and spring conduit protecting the harness and a UL10C listing behind it. This is access control hardware for institutional and commercial doors, not a residential item.
