WW: Electric Hinge

Sigh…what do you have to say about this Wordless Wednesday photo, sent to me by Joe Cross of Allegion?  The screw below the hinge leaf is to keep the wires from getting totally squashed.

    nice find, I really dont think your suppose to use wire nuts behind a hinge on a wood frame like this, unless there is enough room in the frame for the power transfer, cant say its fire rated door frame either… (eeks)

    power transfer works best with metal frames, due to there is enough room in the jamb and also in the door for making the connection behind the hinge (of any hardware that uses power transfer) ( i may be wrong, i have not seen the IBC or fire codes about concealed power transfer applications.

    Pure amateur install…

    Looks like they bought crimp connectors from the auto parts store.

    Soldering with offset connections for the multiple wires then heat shrink tube. Then an overall heat shrink tube.

    Done correctly, the connections would be no larger than original wire o/a sheath and would feed right back into the jamb.

    Most people make the mistake of working down the frame to the hinge. This is much easier done by bench soldering leads on the hinge to feed up to your next connection above the door.
