18 AWG Bulk Wire

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 a standard commercial-grade thickness used for years in the industry.

The SPT-2 insulated bulb wire has a slightly thicker insulation 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.

The maximum line length of 18 AWG wire is 250 feet regardless of the type of bulbs installed.
