But you can't just consider the tub size â they're all designed to be dropped into a deck, and that will take up more space, with the bare minimum adding at least a half-inch to your measurements on all sides.
Report Abuse. Scope: Dielectric Strength is a measure of the electrical strength of a material as an insulator. Dielectric strength is defined as the maximum voltage required to produce a dielectric breakdown through the material and is expressed as Volts per unit thickness.
Part of the Electronics glossary: The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.
