Bulk Wire - 18 AWG 1000-foot spools

How do I insert spaces into my C7 and C9 strings of lights? What do you suggest I use for a professional finish to my Christmas lights installation?

Our 1000 foot spools of 18 AWG wire come are made with either SPT-1 or SPT-2 insulation and are tailored for the Christmas light installation professional who is using this wire in conjunction with our 500 or 100-foot spools. Cutting the wire to fit, makes for a precise installation.

You can use this wire to span spaces or extend your customer installations. Be sure to consult with a master electrician on any project that requires electrical customization.

What exactly is the difference between SPT-1 and SPT-2?

SPT-1 insulation is standard commercial grade thickness used for years in the industry. The SPT-2 insulated bulb wire has a slightly thicker insulation that is suited for commercial off-season applications and is popular with our customers who own restaurants and shopping malls.

No matter what thickness of insulation, the wire is still rated at 10 amps. (There is some misinformation floating around the web that SPT-2 has a higher current rating. That information is incorrect.)

As with all of our cut to fit and customer commercial spools, consult with a master electrician during installation. The maximum line length of 18 AWG wire is 250 feet.
