Whereas an indecent ELCB - like the one that used to be on nb Lark
Rise, fails quietly during the winter while no one is looking and
causes problems for marina managers in the spring when boaters wander
about claiming that the mains circuit to their mooring must be
faulty. Still, at least it was straightforward and inexpensive to
replace.
