The Item in My Kit

I bought BOJACK 400A MEGA Fuses as part of my camper van equipment.

The 400-amp BOJACK fuses are one of several separately identified fuse purchases in my electrical kit. Keeping each rating in its own item record makes the parts list easier to follow.

Keeping the Fuse Rating and Bolt-on Format Identifiable

  1. I bought fuse supplies separately from the smaller routing components.
  2. The kit included blade, cartridge and bolt-on fuse formats as distinct items.
  3. This BOJACK purchase specified four-hundred-amp MEGA/AMG strip fuses.

My Takeaway from This Job

All three choices here retain a four-hundred-amp bolt-down MEGA format. The differences are brand and package rather than a change in marked rating, making them easier to compare within this one fuse group.

These options retain the same marked rating and bolt-down fuse family.

Product Details And Van-Build Uses

Listed Current400 A
FormatMEGA/AMG-style bolt-down ANM
Retailer Dimensions68.85 × 19.2 × 10 mm

The 400A BOJACK entry identifies a specific fuse rating within a family of similar-looking bolt-down parts. The retailer describes the MEGA/AMG-style body and gives its mounting dimensions. For a van parts list, keeping the 400A purchase beside its holder record makes later inspection easier. Record the body marking, holder identity and circuit label together, then retain the product reference with those notes. A matching outline does not by itself make a different current rating the same purchased item.

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.
