Product Knockout: UL1061 vs UL1007

Product_KnockoutOur Product Knock-out series is a match-up between two similar products. In boxing terms, think same weight class, same caliber, and same level of experience and amount of exposure. The purpose of these posts are for you to see a side-by-side view of two similar products, and to understand which one will be crowned champ for your specific purposes. Take your seats and prepare for battle, because the gloves are coming out.

UL1061 wire and UL1007 wire are both UL approved, single conductor wires commonly used for the internal wiring of electronic equipment. They are part of the classification known as hook-up wire and lead wire; they’re both similar in size, material, and overall construction.

Read on to discover the differences in construction and electrical specs between these lead wires:

UL1061 vs UL1007 Specs for Construction
UL 1061 UL1007
Conductor Size 14-30 AWG 16-32 AWG
Conductor Type Solid or Stranded Solid or Stranded
Conductor Material Bare or Tinned Copper Bare or Tinned Copper
Insulation Thickness .009” (9 mils minimum average thickness, 7 mils minimum thickness at any point.) .016” (15 mils minimum average thickness, 13 mils minimum thickness at any point)
Insulation Material Semi-Rigid Polyvinylchloride (SR-PVC) Polyvinylchloride (PVC)

The construction of these wires is similar in that they both feature a single conductor and insulation. They both can have solid or stranded copper conductors, which can be bare or tinned, but are made with different insulation materials—UL 1061 comes in SR-PVC and UL1007 comes in PVC insulation, both of which are extruded.

The most noticeable difference between UL 1061 and UL1007, aside from the insulation material, is the insulation thickness, which affects the overall weight and size.

UL 1061 UL1007
Max. Temperature Rating 80°C 80°C
Max. Voltage 300 300

The electrical specifications of  UL1061 and UL1007 don’t vary at all; both have a maximum voltage of 300V and comparable temperature ranges. Both wires also pass the UL VW-1 Flame test.

Due to their construction, these hook-up wires can often be found as dual rated with other UL Styles, CSA Styles and even Mil-Spec styles. Allied carries the following versions:

UL1061 vs UL1007 Dual Ratings & Specs
UL 1061 UL1007
UL Style UL Style 10002 (105°C) UL Style 1569 (105°C)
CSA Style CSA Type SR-PVC CSA TR-64 (90°C)
Mil-Spec Style Mil-W-16878/1 Type B (105°C, 600V)(depending on size and stranding) N/A

The dual rating can extend some of the specifications of a cable. For example, on the sizes where our UL Style 1007 wire is dual rated with UL 1569, it can be rated to 105°C when used in an application where UL approval is required. When AWC’s dual rated UL 1061 wire is used in a mil-spec environment, it rated up to 105°C and 600 volts.
