An electrical box includes an enclosure having a bottom wall and a peripheral wall extending away from the bottom wall in an axial direction of the enclosure to define a cavity of the enclosure with a front opening of the enclosure providing access to the cavity thereof. A retainer wall extends axially from the bottom wall and is spaced from the peripheral wall with respect to an inward direction of the enclosure arranged transverse to the axial direction thereof. A clamping element is positioned and maintained in a clamp opening formed between the peripheral wall and the retainer wall by a press fit with the clamping element applying a clamping force to an electrical cable extending through a gap formed between the peripheral wall and the clamping element.
