Which statement reflects heating behavior independent of the ON/OFF state when 115VAC is applied?

• A. The drain masts heat whenever 115VAC power is applied to the controller, regardless of the ON/OFF state.
• B. The drain masts heat only when the ON/OFF state is ON.
• C. The ON/OFF state has no influence on heating when 115VAC is applied.
• D. The drain masts never heat.

Answer: (A)

Heating is driven by the presence of the 115 VAC supply, not the ON/OFF control. When 115 VAC is applied, the heater draws current and warms the drain masts regardless of whether the ON/OFF switch is on or off. This happens because the heating element is tied to the power line in a way that isn’t interrupted by the ON/OFF control, so heat generation occurs as long as the supply is present. The other statements imply the heater depends on the ON/OFF state or deny heating altogether, which doesn’t match this wiring behavior.
