 In addition the stage pin connector has an increased durability and resistance to damage due to its more robust construction and the ability to compensate for wear with a pin splitter.Having a distinct connector designated for dimmable power also helps prevent confusion of dimmed and non-dimmed circuits which could lead to equipment damage.Even the smallest stage pin connectors are rated for 20 A, which translates to 2.4 kW at 120 V, compared to the 15 A and 1.8 kW of the NEMA 5-15.
