Trouble
Overheating
26
Cause
Overload
Poor Contact
(Contact out of adjustment)
Connections to Switch not of
adequate current carrying capacity.
Contacts Burned or Pitted
Bolts and Nuts of
Connections not tight
Located in too hot an ambient
(40°C Max.). (Such as too close to
a boiler, a furnace or the like)
Do not exceed 40°C as maximum ambient temperature.
If the switch is overheated because of excess current,
one of two remedies can be adopted:
Replace with a switch of rating adequate for
the present or future loads, or:
Rearrange circuits to remove excess load.
Adjust Contacts (See Section 4.11.1)
Increase the capacity of the connections by adding
conductors or by replacing with heavier conductors.
Contacts should be dressed and fitted properly.
(See Section 4.11.1)
Tighten all bolts and nuts. (Do not exceed torque as
per Section 4.2 by more or less than 10 percent. Over-
tightening bolts may cause bolts to exceed their elastic
limit, leading to more loosening of the connections.)
Relocate in a cooler place or arrange some means
of cooling.
