Which statement is not true regarding fuse mountings?

Explanation:
Fuse mountings are designed to match specific fuse classes, so a fuse should only be installed in a mounting that is intended for its class. Class J fuses are designed to fit only Class J mountings; the contact sizes and geometry, along with the mounting features, are different from those in Class R mountings. Attempting to place a Class J fuse into a Class R mounting can prevent proper seating, lead to an unsafe connection, and affect the fuse’s performance. The other statements reflect standard compatibility: Class J fuses in Class J mountings, Class R fuses in Class R or Class H mountings, and many fuse types being current-limiting and so marked.
