  • Built-in test signal generator makes troubleshooting easier
  • Intellisense feature ensures top performance

Essential Info

Stop pulling your hair out trying to figure out why some X10 receivers don't respond to X10 transmitters. Resolve the problem AND make troubleshooting easier with a powerful amplified X10 coupler-repeater for 2-phase (split single phase) electrical systems that even sends and receives test signals! Just like other coupler-repeaters, this unit helps X10 signals cross the two separate 120V legs of power found in most homes. But this revolutionary unit goes a giant step further by offering signal and error LEDs, as well as a test button that generates an ON/OFF signal. These added features allow for easy signal strength verification at individual module locations with a signal strength indicator (sold separately).


What's Included

  • Leviton 2-Phase X10 Coupler-Repeater

  • More Info

    This X10 coupler-repeater is similar to a non-amplified signal bridge, but with the added ability to regenerate an X10 signal and blast it out both legs of electricity simultaneously. Provided there is at least 100mV of incoming signal, the unit will boost the outgoing signal to 5-7 volts across, depending on the impedance of the home. An LED will blink when X10 signals are detected and repeated to let you know it's operational. Plus, Leviton's exclusive Intellisense™ (gated automatic gain control) feature helps ensure top performance even when noise is present on the AC line.

    The module should be installed at the main panel where electrical service enters the home. You will need two dedicated 15-amp circuit breakers (available at a home improvement center).

    Is this something you can install yourself? Absolutely! If you've ever replaced a broken circuit breaker, then you have the experience to install it. It can also be installed by an electrician, typically taking no more than an hour of labor time to mount and wire it.

    Note: Not for use with 3-phase systems commonly found in commercial buildings, apartments and condominiums. Use the X10 Signal Amplifier/Repeater or HomePro Amplified X10 Coupler Repeater with Repeated Signal Detection for these systems.

    Arrived as promised and quickly. Installed and working.

    So far everything is working fine. It will not, however, fit in a 3 gang switch box (rework box) as advertised unless pushed in with great force.
    CLIFF -- sanford, ME   3/23/2013
    Item recived in good condition with fast shipping. Instructions were easy to follow and device is working as expected. No issue.
    FROM THE -- waterford, ON   2/3/2013
    Easy install (Well except it does not fit in a standard electrical box) and filled the voids in my automation coverage
    ZACK -- benicia, CA   1/11/2013
    I installed in my X10 split-phase 110v/220v and it was constantly transmitting an ON signal to one of the appliance modules making my system unusable. I had to return it for a refund.
    KIRK -- cuyahoga falls, OH   12/13/2012
    Originally ordered a Homepro Signal Bridge HPCP (CP000) to replace an X-10 that got damaged. I have a smaller home(less than 200sq. ft.) but I wasn't able to get the passive bridge to work. Maybe too much line noise? RMA'ed the unit with no hassle. So I then ordered the Leviton HCA02-10E 2-Phase X10 Coupler-Repeater. This unit works like a champ! X-10 signals are re-transmitted between the two phases. The "test signal" feature is nice too. It allows you to send a repeating "on/Off" signal to a specific code(don't remember what it is off hand though). That helps while troubleshooting/setup of the repeater. I wish the passive coupler would have worked to save a few bucks, but the HCA02-10E is priced better than X-10 repeaters that are discontinued(if you can find them).
    DOUG -- alanson, MI   12/3/2012
    Product received in a timely manner. Installed per instructions. My x10 products now work across all my circuits.
    JOHN -- hastings, MN   11/22/2012
    Good device, does the job it's suppose to.
    Mike -- pottsville, Pa   11/12/2012
    Instant Success!! Absolutely corrected a multitude of X-10 problems. I recently pruchased a couple of new TV's and they must have sucked up all of my signal.System works super now.
    BARRY -- somerset, NJ   10/7/2012
    So far this is the best phase coupler I have used. The others lasted only a few months and then they were useless. I have faith in Leviton products and hope this will last a long time.
    KEVIN -- san jose, CA   3/29/2012
    the price was high, but I guess it's hard to argue supply & demand since you're the only one's that still carry it. Arrived promptly and worked like a charm
    RICHARD -- clarksburg, CA   3/5/2012
    I've used these before. They make X-10s work!
    DANIEL -- prescott valley, AZ   2/11/2012
    I had installed one of these a few years ago and it solved all of my X-10 communication issues. My X-10 controller is plugged into a duplex in the den (not the one with the computer power surge protector of course). We have many X-10 light switches and lamp controllers on both phases. A lighting storm apparently took out the former HCA02-10E, so I purchased am X-10 Pro XPCR phase coupler. It did not solve the problem. I then purchased two HCA02-10E units, so I would have a spare, and now everything is back to normal.
    JOSEPH -- cranford, NJ   1/12/2012
    Works Just the way it is suppose to. In combination with the X10 PAT01 X10 Signal Converter and 16 Device RF Base all my coverage issues are solved.
    JOHN -- wilton, CT   12/29/2011
    As expected
    ROBERT -- pembroke, NH   12/19/2011
    This unit appears to have rejuvenated my 20 year old X-10 system.
    RICHARD -- monument, CO   12/11/2011
    Not designed for newer 3-gang boxes with sloped backs; no way to secure the coupler in the box (no tape provided despite instructions). Did not completely resolve X-10 devices' responses, despite no error (no red light indicating excessive noise); several X-10 devices still operating sporadicly, even after replacement with Smarthome switches.
    DAVID -- fairport, NY   11/17/2011
    Without this coupler-repeater, there were parts of our house that X-10 signals wouldn't reliably reach. I tried coupling the phases with disc capacitors, which improved the situation marginally. Once I installed this device X-10 worked reliably through out the house. That was 3 years ago. But, unfortunately, that unit recently failed (that is why I rated this 4(* - not 5*)so I purchased a new identical unit from Smarthome. Note: I had an interesting problem with the original installation of the coupler-repeater: My X-10 sent out signals to two different devices at 11 pm. One of the devices wouldn't shut off. It turns out that my controller was sending out the 2nd "off" signal while the repeater was sending out the first - CONFLICT! Problem was simply resolved once I advanced the first "off" in my controller program.
    DOUG -- highlands ranch, CO   7/17/2011
    This is the 2nd phase bridge I have purchased from you--installed by an electrician, and it does not solve the problem. Would lile to return the item. Any solutions so that bath phases can see my controller????
