The Item in My Kit

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

My purchase list separates this quarter-inch-stud lug from the 5/16-inch version. That small hole-size difference matters when keeping similar-looking connection parts organized.

Keeping the Cable Size and Stud Hole as Two Dimensions

  1. My electrical kit separates bulk cable from its termination supplies.
  2. I bought several lug sizes as distinct items.
  3. This SELTERM pack pairs a four-AWG barrel with a quarter-inch stud hole.
A grouped roof-wire connection before the final conduit work.

My Takeaway from This Job

The other SELTERM pack retains the four-AWG cable barrel and changes the stud hole to five-sixteenths inch. TKDMR instead groups several lug sizes with tubing, so the choice is one explicit combination or a mixed supply.

The cable barrel and stud opening remain separate dimensions.

Product Details And Van-Build Uses

SpecificationProduct Detail
Cable Barrel4 AWG
Stud Hole1/4 inch
BodyTinned copper ring lug

The quarter-inch hole makes this four-AWG lug a different terminal choice from the five-sixteenths-inch version. Keep those similar-looking parts separated in the organizer and identify the hole size in the cable-end list. For a van board, the physical lug footprint and the cable bend should appear on the mounting drawing. The manufacturer reference provides another way to compare the exact variant, while the purchase record retains which version belongs to this page.

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.
