    you just need a multimeter to see if it's running at 208 or 240. that will tell you what light you can run and how many watts you have available. you obviously won't be able to use the heater

    I would just pay the light bill I can only see a fire hazard happening really and how many watts is the heater running anyway? Either way it don't cost that much to run just over 1,000 watts.

    T104 timer question :

    - i will be wiring the timer with 10-3 dryer wire to a 30 amp breaker.
    - I understand where the the timer clock connections go as well as the 10-3 wire.

    i want to know what gauge wire is recommended from the #2 and #4 terminals to my one junction box that will house 4 240v plugs ?

    i realize if i put just 120v standard plugs in junction box i'm using 14-2 wire. i'm assuming 12 gauge is not necessary in the 240v plugs.

    a response would be greatly appreciated

    No, what gauge wire is the extension cord if it's not rated to carry the load could cause a fire

    From what I know it's a 10amp lead, I found another lead that is 15 metres instead of 20 and this new lead is 15AMP do you think this new one is suitable? Sorry to be a pest, I just don't want a fire that's all

    Rule of thumb find a watts to amps converter calculator and it will let you know how many ampa youre pulling then go get a cord at least double the amps to be on the safe side
