REVERSIBLE TERMINAL BLOCK FOR IMMERSION HEATER ABSTRACT OF THE DISCLOSURE A reversible terminal block for an immersion heater which facilitates wiring in the field by providing a disc-like body with parallel axial bores, arranged in spaced, circular configuration, for receiving six leads from three looped elec- trical heating elements and the ends of a pair of associated thermowells, the one face of the block being substantially flat and adapted for single phase wire-up, and the opposite face having a recess for accommodating a connecting strap extending between two of the bores so as to position the strap in the recess at a different level from two associated straps for connecting adjoining pairs of heating element leads thereby permitting wire-up for a three phase load connection without the need for separating insulation, by merely reversing the block and positioning it to receive the leads in the proper bores.
