reviewing the panel design budget. The specification calls for a 2500A main service entrance breaker. You find two options: Option A (MCCB): Cheap, compact, and rated for 2500A. Option B (ACB): Massive, bulky, and five times the price. The question inevitably lands on the electrical engineer&#8217;s desk: &#8220;Why are we paying so much for the bulky one when the cheaper one has the same voltage and amp rating?&#8221; The answer is simple, yet invisible on the nameplate: **The Interrupting Capacity (Icu).** You aren&#8217;t comparing the ability to carry current (the amp rating); you are comparing the ability to survive an explosion.
