The Nema 7 electrical construction is designed for explosion proof
were required. The Nema 7 enclosure are capable of withstanding
and containing internal explosions so that an explosive atmosphere
surrounding the enclosure will not be ignited. Enclosed heat
generating device shall not cause external surfaces to reach
temperatures capable of igniting explosive surrounding atmospheres.
