What size and type wire should I use?

I'm looking to run an outlet(to run a battery charger or radio) and couple of lights(one light would be a 500w flood light the other would be just a 60w bulb) from my house to a gazebo 350' away. I'd bury the wire, and plan on putting it in PVC conduit. What type and size wire should I use for this project?

The smallest circuit you can run for an outlet is a 15A, #14 wire. But at that distance, I would use #12. Single conductor wires are needed in a conduit, as opposed to an MM cable.

Personally I'd go with #10 or #8 and run a multi-wire branch circuit.

For one, a MWBC will lessen the problem of voltage drop, and second, you never know what someone will plug in down there, so wire it as if someone will be using a circular saw some day.

i'm not sure what the voltage drop limits are in the states but #10 comes in a 5.8% and #8 comes in at 3.7%. You would have to use a #8 in canada i believe.
i'd put a 1" pipe in. Just makes life easier :D

Typically in the States we will figure the VD to max of 5% but 3% is most common numbers there are few case it can have more than 5% but it is very I will repeat this very rare.


Just stick with 6.0mm˛ or 10mm˛ { #10AWG or #8 AWG } and run in multicircuit fashion and yeah of course you will need RCD { GFCI } recepetale at the end of run { don't bother use the RCD breaker due the distance it can make a false trip unless you have it in the subpanel }

The reason why as SpeedyPete mention one item and also some case someone bring the monster sized boom box to crank up a bit that can take some bit of serious juice as well.
