*Explosion-proof or Flameproof? Which is it?
Both terms are correct and are used interchangeably, where Explosion-proof is the vernacular used in North America, while Flameproof is the preferred International term. This protection method is used to contain an explosion from within the enclosure and to prevent sparks from within its housing from igniting any gases, vapors, or dust in the surrounding atmosphere.
What is the difference between an Adapter and Reducer?
Basically, Adapters have a smaller male thread than female thread, whereas Reducers have a larger male thread than female thread. Adapters are used where the size of the connection device or cable gland is larger than, or equivalent to in size, to that of the conduit entry thread of the enclosure.
Reducers are employed where the size of the connection device or cable gland is smaller to that of the conduit entry of the enclosure.
