Has anyone figured out how many (if any) watts this coupler contributes to the power bill? Also does it work better on a 220V breaker or two 125V breakers? Has anyone used existing circuit(s) to piggy back onto for the install? Has anyone had a encounter with the electrical inspector after he/she discovered this coupler was installed? If all X-10 devices were controlled only via HR-12A remotes could you not circumvent the XPCR by installing 2 TM751 transceivers plugged into outlets on both phases of the electrical service? TIA for any help received. https://www.55[ restricted ]/cheap-color-copies

Have not measured a XPCR's power. Since it has a capacitor derived supply. You would need a true sine wave meter to get an accurate reading.

It should not matter if you used a single 220V or pair of 120V breakers. The 220V connects to both phases and the 120V pair has to have one on each phase. Either way the XPCR has a connection to both phases of the homes wiring.

The TM751 does not have a power line receiver in it and is not polite. So if by chance both TM751 modules received the same HR12A command. Both could step on each other and garbage the power line commands. If the power line command was able to reach both phases and not each one only doing one of the phases. With no XPCR in the system.

The RR501 has a power line receiver in it and is polite.

It is also possible that the TM751 modules would not see the HR12A and half the system would miss things. The X10 RF is not known for great distance communications.

Jeff has a great set of X10 tutorials that may give you some added information.

You can also find more X10 data on their forums and Wiki.

The 6201 Leviton version of the XPCR says 5 Watts.

My tests maybe flawed due to the capacitor derived power supply. True RMS Meter. White Neutral and RED Line. As it is the Line that also powers the main power supply. 14.65 Watts. The two Black wires are to couple the X10 to and from its Line connection and probably does not draw much power.

One thing I did find out in Feb. 2018. While doing some tests. Make double sure you have a good Neutral power connection. Mine opened up and the 220VAC between the Red and Black wire being used. Shorted the MOV voltage protectors. Burning them out and blowing the internal fuse wires for the two lines being used.
