Electrical Protection #
Flameproof enclosures are tested for their ability to withstand internal gas explosions only; they are not capable of withstanding the energy which may be released as a result of an internal short circuit. In order to avoid invalidation of the certification, it is important that properly rated/calibrated electrical protection, e.g. fuses and/or circuit breakers, are utilised.
Environment Protection #
Flameproof machines are not always rain or waterproof. Ingress of rai through joints and gaps can be minimised by using gaskets or ‘O’ rings, which must be part of the design.
Suitable tape can be applied around joints.
