The Item in My Kit

I bought SELTERM 4-AWG 5/16-Inch Cable Lugs as part of my camper van equipment.

My electrical kit includes lugs organized by both cable size and stud hole. This SELTERM purchase is the 4-AWG, 5/16-inch combination, separate from the quarter-inch and larger-cable lugs on the list.

Comparing the Cable Barrel and Stud Opening Separately

  1. The roof project involved preparing and routing several device leads.
  2. My larger-cable termination supplies were separate purchases in the electrical kit.
  3. This SELTERM pack specifies a four-AWG barrel and five-sixteenths-inch ring opening.
A grouped roof-wire connection before the final conduit work.

My Takeaway from This Job

The wire-entry size and the stud hole describe two different ends of a lug. SELTERM and Sanuke supply the same stated size combination; TKDMR changes to a mixed lug-and-tubing assortment.

Cable barrel size and stud-hole size are separate lug dimensions.

Product Details And Van-Build Uses

SpecificationProduct Detail
Cable Barrel4 AWG
Stud Hole5/16 inch
BodyTinned copper ring lug

This lug combines a four-AWG cable barrel with a five-sixteenths-inch ring hole. Those are separate dimensions, so both belong in a cable-end list. When laying out a van electrical board, show the flat ring area as well as the cable route behind the barrel. The matching SELTERM reference keeps the tinned product identifiable among bare-copper, wide-pad and other stud-hole choices. Keep that identity with the completed cable label for future work on the board.

Does Four AWG Describe The Stud Hole?

No. Four AWG identifies the cable barrel; the stud hole is the separate 5/16-inch dimension.

Questions from My Build

What Connected the Roof Equipment to the Van Entry?

A PVC conduit layout with boxes, fittings and cable glands.

What Did I Do at the Small Junction Box?

I drilled the box for a threaded PVC fitting and arranged the light-wire connections inside that part of the route.
