BTW, I am in Canada and we essentially have the same type or wiring system.

(The NEC is not exactly the same as the CEC but it is close enough...)

I'm no electrician but you usually have two phases in an house (you need 
two phases for your electrical stove and dryer which need 220/240V).

There are tricks that apparently couple both of them together (see 
http://kbase.x10.com/wiki/Phase_Coupling, please take its content with a 
grain of salt though since it's from X-10's wiki). That trick works with 
X-10 but should probably work for powerline as well...

One of the tricks is apparently to put a suitable size cap(acitor) 
between both phase... If you go that way I would suggest going with a 
professionnaly made product though...

I would suggest you look at reviews before making your choice as they 
are apparently of varying quality...

The ones I tried were Netgear XAV101 which no longer exist I think... 
Only bad thing I have to report is that one of them lost its settings...

It worked for me in SD, can't say anything about HD...

Have a nice day!
