WASHERS
Any bolted "pad to flat" electrical connection
should include a bolt, two flatwashers, and
the nut. In addition, if any of the flat compo-
nents is aluminum, a properly designed
Belleville washer should be interposed
between one of the flatwashers and either
the bolt head or the nut, with the hollow of
the Belleville washer placed against the flat
washer. BURNDY

Belleville washers are
designed to maintain substantial force when
tightened to NEMA - recommended values
and finely finished to avoid galling.
The stainless washers are 301 stainless steel.
