What is the maximum kW element typically used on each contact of a residential heat sequencer?

In residential heating systems, heat sequencers are designed to control the operation of electric heating elements sequentially for efficiency and safety. Typically, each contact in a heat sequencer is limited to handle a maximum of 5 kW. This design consideration helps manage the electrical load and ensures that the wiring and the sequencer itself do not overheat or become damaged from excessive current.

Using a maximum of 5 kW per contact allows for adequate voltage regulation and minimizes the risk of tripping circuit breakers or fuses due to too high current draw. This limit also facilitates the safe operation of multiple elements in a heating sequence without exceeding the overall system capacity or compromising system efficiency.

Larger values, such as 10 kW or 15 kW, would lead to complications in residential systems, as they would necessitate heavier wiring and more robust circuit protection, which are not typical in standard residential applications.
