Deck lighting


Im looking to string together some lights and place them on a electric time to be turned off and on automatically at night. Im a newb when it comes to electricity so I wanted to see if a professional had any input on how many lights strung together were safe with the equipment im using.

I want to use this timer...
http://www.amazon.com/Intermatic-TN7...8449710&sr=8-8

And these lights...
http://www.homedepot.com/webapp/wcs/...016+4294887768

And 16 guage wire to string them together.

How many can I safely string together and not have to worry about overloading anything when plugging them into a regular wall socket?

Thanks!

What are you going to install the bulbs in - socket/lamp assembly?
Where/how will these be mounted on the deck?
Temp installation - summer?
I think any inspector woudllwant 14g wire rated for outdoor use & permanent fixtures

They will be installed via this type of sockets...

The use will be for an outside porch.

That means that the wiring you want to use (as far as I know) does not meet code

When a building is under construction these use something like that as Temp lights

Need an electrician/code person to weigh in
I know soem codes - but not all

Well this will not be permanent. I am just making sure I don't burn anything down. I am looking for a quick fix while I am in the process of figuring out what permanent fixtures I want. 6-8 would be ideal but can do less if its not safe. Thats a total of 184 watts max and im not really sure of the amperage of the lights or how to calculate it. I am also not sure if there is another measurement that I need to look at.

The problem is that all splices must take place in an approved box

How many lights you can connect is limited by:
#1 Circuit size: 15a = 1800watts, 20a = 2400 watts
#2 Fixture - Max bulb that can be installed

That connection indicates 660w Max - doesn't seem correct
I'm not sure a CFL bulb can be left exposed to the weather
Mine are all located inside of a fixture

The CFL lights will be on an enclosed porch so the only thing weather wise that they will be exposed to is the temperature. Plus since they are a temporary solution im not sure how long they are even going to be used. So assuming that the limiting factors above are correct then I should be fine running 8 lights as long as the wiring is adequate. Is 16 gauge wire adequate?

No, 16 AWG is not adequate. This circuit will be protected by a 15 or 20A breaker, so a minimum of 14 AWG or 12 AWG wire is needed. Those sockets are the wrong choice, too. They require individual wire-nutted connections at each socket, which cannot be made to code (or even safe, really). I would really recommend not doing this - you don't seem to have enough electrical knowledge to make a safe installation. Why don't you just buy a premade light string? Plenty of places sell them. I've even seen them at Lowes.

If you insist on making your own light string, use a socket like this:
http://www.lowes.com/lowes/lkn?actio...P-L&lpage=none

It self-pierces the insulation on the wire, so you don't need to make connections at each socket and the wire is continuous for the whole string. You can easily suspend the sockets from their hooks, so the weight is not resting on the wires. Use 12 AWG THHN wire. Be sure to insulate the cut ends at the far end of the light string using wire nuts. Technically, that kind of light string should not be connected with a plug since plugs are not listed for use with THHN wire, but that's what you'll have to do to connect to the timer you have chosen.

Make ABSOLUTELY SURE this is connected to a working GFCI circuit. Light strings like this pose a much greater shock hazard than most other types of installations, and a GFCI is really a necessity.

Your timer is rated for 1675W (14A), so you could use up to that much lighting. With CFL, that's a very large number of lamps. Overload will not be an issue.

210.3 Stated that the minimum branch circuit is 15 amps thus 14 gauge wire.

590.2 Except as specifically modified in this artical, all other requirements of this code for permanent wiring shall apply to temporary wiring installations
