Twenty amps, and every number that has to go with it.

The set of figures

20 A. One metre of 2.5 mm² cable. A 20 A fuse already in the fuse box. Ring terminals with an 8.2 mm bore. Red positive, black negative.

Five numbers that fit together. The rating matches the cable, the fuse matches the rating, and the ring bore tells you whether it goes on the battery stud.

That coherence is the point. A socket rated 20 A on 1 mm² tails is a 20 A socket in a circuit that is not, and the tails are what decides.

What it powers

A compressor. A cool box. A tyre inflator. The loads the 5 A socket in this family cannot take.

Marine grade

Named in the title, for boats, trucks, campers and motorcycles. Splash-protected and dustproof.

Described, not rated — no IP figure, which is the same gap all four sockets here share.

The lines this listing leaves blank

The panel cut-out. It has to be measured from the part.

And any warning about lighter elements. The cheapest socket in this family says a lighter would burn it; this one, at four times the current rating, says nothing either way.

German, French, Italian and Spanish Amazon stores quoted 11 € to 12 € when this page was compiled.
