FEDERAL LAW
183.420 - Batteries
(g) Each battery terminal connector must
not depend on spring tension for its mechanical connection
to the terminal. |
The integrity of the battery terminal connections
is very important to prevent sparking and overheating of the
terminal. Failures of a battery terminal connection could
result in a fire and explosion hazard.
By prohibiting spring-type battery terminal
connectors, the regulation requires the use of mechanical
connections that are not likely to loosen due to vibration.
There are two types of battery terminal connections
in prevalent use. They are the clamp type, and the bolt-on
type. Figure 17 depicts these types, as well as a spring-type
which is
PROHIBITED.
TO COMPLY WITH
THE LAW
- Is each battery terminal connector
provided with a mechanical terminal connection that
does NOT depend on spring tension?
