1. A cable limiter comprising:
a main body including a cavity;
a replaceable fusible element, the cavity of said main body being structured to receive said replaceable fusible element;
and
an annunciator housed by said main body, said annunciator structured to annunciate status of said replaceable fusible element,
wherein said annunciator comprises a piezoelectric transducer and a voltage sense circuit structured to power said piezoelectric
transducer responsive to voltage across said replaceable fusible element said replaceable fusible element includes a predetermined
current rating and a member sized as a function of said predetermined current rating; wherein said cavity includes an aperture
sized to receive therein only said member of said replaceable fusible element having said predetermined current rating; wherein
said main body includes a first conductive end member and a second conductive end member, said first and second conductive
end members removably mounting said replaceable fusible element; and wherein the member of said replaceable fusible element
is between and offset from said first and second conductive end members, which mount said replaceable fusible element.
