Abstract: Industrial electric ovens and fryers of the type used for cooking precooked foods such as meats prior to packaging of the food draw high currents which tend to melt internal electrical connections. An industrial heating device includes compression-type electrical connections which reliably carry high currents and are capable of withstanding high voltage levels without breaking down. Compression-type electrical connections are used instead of the screw-type connections of the prior art to insure that all electrical connections have reliable, relatively large current-carrying cross-sectional contact areas. The electrical connection matrix of the resulting industrial heating device has increased current-carrying capacity and is much more reliable and resistant to electrical failure.
