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.
The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground.
