Selecting the right enclosure
Choose an empty enclosure by lid type and dimensions when the box is equipped to a component list, or one of the instrument and telecom enclosures by number of pairs or triples and signal type. For Tranberg’s own Ex eb junction boxes in smaller sizes, see TEF 1058; the heat trace switch boxes on the same enclosure are found under switch box.
