Abstract: A housing for a meter is disclosed. The housing includes a base portion which has an insertion axis along which the base portion can be inserted into an opening in a panel and an interior space for receiving electrical meter components. A flange extends laterally outwardly from the base portion and one or more resiliently flexible flaps extend from the base portion and are free to flex laterally inwardly about an axis generally parallel to the insertion axis and towards the base portion to permit passage of the flap or flaps through the panel opening when the base portion is inserted into the panel opening. The flap has a panel abutting surface that is axially spaced from the flange and at least partially laterally coextensive with the flange to define therebetween a slot or gap for receiving a portion of the panel adjacent the panel opening.

Abstract: An electrical meter, comprising a housing, a motor magnet mounted relative to a housing for pivotal movement, and an induction clip having an arcuate portion of more than 180 degrees, opposite ends of the arcuate being anchored to the housing to define an area within which a conductor is maintained within the radius of the arcuate portion.

Abstract: The electrical measuring meter comprises a polarized motor magnet mounted for movement to and from a starting position, a polarized holding magnet operative magnetically to influence the motor magnet constantly towards such starting position, and a calibrating element magnetized by the holding magnet to effect a partial cancellation of the holding magnet's influence on the motor magnet as is needed for calibration. The calibrating element preferably is in the form of a soft iron circular disc, and soft iron discs of different sizes are used to calibrate the meter for respective different maximum scale current values. Also, the high magnetic permeability of the soft iron disc enables the use of a rugged and economical sleeve bearing mount for the motor magnet even in a meter calibrated for low current measurement.
