I have problems getting signals from one
room to another and extremely hard getting
across electric phases. I have used phase
bridges andthey don't work.

Maybe a noise problem. Try selectively
unplugging things like TVs Computers Surge
Strips. All can generate noise or absorbe
signals. My APC BX1000 UPS has a surge
suppressor in it thet absorbed over 60% of
my signals. I had to add an X10 Type Line
Filter to it's AC Line Input.

Brian,
What is the X10 Type Line Filter and where
do you get them.  I have a floodcam with a
chime and the chime works during the day but
not at night when the flood light comes on.
Will the phase Coupler & Amp help these
problems?
Thanks,
AL

I got mine from.
www.automatedoutlt.com
Mine is a Smarthome 1626-10 10 Amp one.
There is a 1626 that is a 5 amp. ACT makes
the AF120 that is a 15 amp and has an
external fuse if you accidently blow it. I
know that X10Pro also makes one but the part
number I don't remember.

This probably sounds like a stupid question,
but, how would I know how many amps I would
need in a line filter?

An older question on the board, but certainly one that a lot of non-technical users would probably have.

All electric appliances have a power rating label.
So basically add up the maximum current totals:

• Some appliances state that maximum Current directly
• Some appliances state WATTS, so Current = WATTS / 120
• Some appliances state VA... this is basically another way of stating AC WATTS*... so Current = VA / 120

If the total is less than 5, then the 5 Amp filters will do fine, else use a larger one that your total will be less than.

*Worse case (as shown) is what you should use when determining current for a filter... VA Amps will actually be less than worse case depending on if the load is inductive or capacitive.

Some filters have a built in slow blow fuse; Smarthome's for one. So momentary motor surge currents on startup should not be a problam.
Filters not made for the X10 signal band may kill the X10 signals while others here have used generic filters with no problems.

Your problem is probably relatively simple.  Most electronic appliances (toys) have input filters on the power line as do UPS s etc.  First pick several units that are very marginal or do not work.  Then unplug all of your electronics.  They work the X-10, it probably works just fine.  Then slowly start plugging in the electrons and keep testing the X-10, you will eventually find your problem(s).
