This has me puzzled - its also late here, so that might be the problem.
How does a timer like this http://www.smarthome.com/images/4253adgm.gif work - without a neutral connected to the timer. As in, when the light is off - the timer is still on, without a compleated circuit. Or is the power to the light very small.
Thanks :p

Re: Timers without neutral
That's entirely possible. It's also bad form to have a load never completely disconnected. it's also possible that the timer is connected between line and ground- also bad form and incompatible with GFCI.

Re: Timers without neutral
the lamp provides the neutral to the timer..and there is a small ammount of current being sampled
many of Plug-n-Power / X10 moduals work this way for the wall switches and dimmers etc.

Thats what I thought - we actually disconnected the ground and it still worked. So, it didn't make sense immediatly that it could still have power with the lamp off - since there is no neutral in the timer.
Re: Timers without neutral
Just measure the voltage drop over the timercircuit when the lamp is on. You will then see if the timer 'steals' a small amount of the voltage. When the lamp is off, it will still be a small current through it, to supply the timer circuit.
