Description
Constructed with tin-plated brass hardware – not stainless
steel. Manufactured from solid brass with an electroplated
coating of tin: surface retains unblemished appearance
longer than copper, and the corrosion-free surface maintains
maximum conductivity. Busbars are recommended in
ABYC standards:
"No more than 4 conductors must be connected to any stud."
E-9.16.K (10) Busbars provide for safer electrical distribution,
allow removal of any one lead for diagnostic checks.
"Ring and captive spade terminals must be the same nominal
size as the stud.” E-9.16.K (11) Littelfuse busbars have
standard studs with hex nuts.
