Description
Constructed with tin or brass plated hardware – not stainless
steel. Manufactured from solid brass and also available
with an electroplated coating of tin (M-448-02): 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.
