Do all light switches have a load wire?
White wire does not always mean neutral, especially if connected to a regular switch. A switch has to have a load wire, otherwise it wouldn't turn anything on and off. It sounds like you have be dealing with 3-way switches where the white wire is used to carry current.
What happens if you use a large inrush current?
Excessively large inrush current can cause system failures or malfunctions. Exceeding the maximum rated current can also result in destruction. However, by adding a C2 capacitor in parallel with the R1 resistor connected between the Gate and Base of the Q1 MOSFET it is possible to slow the decrease of the Gate voltage, ...
What happens when a load switch is turned on?
When the load switch (Q1 in the diagram below) is turned ON, a large current much greater than the steady-state current will temporarily flow. If the charge on the capacitor is close to zero then a large inrush current occurs, voltage is supplied to the output Vo, resulting in an instantaneous and large charge in current flow. This excessive current is often referred to as inrush current.
What is load switch?
A load switch is an electronic component that has no moving parts, which works somewhat like a relay. Generally, two MOSFET transistors act like a switching element, one of them being an N-channel device, and the other a P-channel device. Below we will cover when that switching element is either ON or OFF, and what that entails.
Why are GFI outlets marked?
Line and load terminals are also clearly marked on a ground fault interrupting outlet because the outlet contains a breaker that interrupts the current when it detects a current surge.
Why are terminals directional on a double throw switch?
The terminal connections are directional on a double-throw switch, on the other hand, because it can transfer power between different loads. The line and load terminals are clearly marked on such a switch, and the live circuit wire must always be connected to the line terminal. Advertisement.
What is load in electrical engineering?
A second meaning for load is the magnitude of the energy consumed by the devices on the circuit. Advertisement.
What is line in electrical?
When referring to an electric device that can be connected to another one, such as a receptacle, line refers to the wires feeding it from the panel, which is upstream from the device in terms of the flow of electricity.
Is it necessary to separate line and load?
Distinguishing between line and load isn't always necessary. For example, a conventional wall switch -- which is a single-pole, single-throw switch -- works equally well whether you attach the live circuit wire -- line -- to the top brass terminal or the bottom because the switch has only two positions -- open or closed.
