The disclosure relates to a field housing for enclosing electrical equipment in installations where there is an explosion hazard. To avoid ignition sparks passing between the inside and the outside of the field housing, the field housing can include a housing cup of a cuboidal shape with a rectangle opening with rounded corners which can be closed with a housing cover. A periphery of the opening can be widened into a surrounding sleeve, and the housing cover can include a peripheral collar of a form and size matching the opening in the housing cup such that a flameproof joint is formed between the collar of the housing cover and the sleeve of the housing cup.
