Fuses should always be connected to the hot wire and should be placed before any other component in the circuit. In most projects, the fuse should be the first thing the hot wire connects to after it enters your project enclosure.

Does a fuse go before or after a switch?
3 Answers. The fuse should always be the first thing a power supply hits when it gets to a circuit. The reason is pretty simple. In the event of a fault that blows the fuse, the power is isolated to where it entered the circuit, thus the whole circuit is protected.
Where does the fuse go in?
The best place to install a fuse in a grounded power system is on the ungrounded conductor path to the load. That way, when the fuse blows there will only be the grounded (safe) conductor still connected to the load, making it safer for people to be around.
Does it matter where a fuse is placed?
It doesn’t matter which end of the fuse holder gets used for going to the battery and which goes to the jack. Fuses don’t require current to flow through them in a certain direction so either way is fine. But typically line is the side that the power comes in on and load is the power going out.
Which is the load side of a fuse?
The load side is where the power leaves the device (or electrical box) and travels down the circuit.
Where should a circuit breaker be placed in a circuit?
While every home is different, circuit breakers are generally located in low-traffic areas of the home, such as a basement, garage, or utility closet. If you live in an apartment, your circuit breaker may be in a more central location, such as a hallway or laundry area.
How is fuse connected in an electric circuit?
i. Fuses are always connected in series with the circuit components to be protected from the overcurrent in the circuit, so that when the fuse blows, or opens, it will open the entire circuit and stop current through the circuit components. This function of the fuse ceases if it is placed in the neutral wire.
Can a fuse be put in upside down?
If you install it backwards, the fuse for the original circuit will supply power to both circuits, and then the power for the additional circuit will flow through fuse 2. If fuse 1 blows, then both circuits loose power. Circuit 2 can overload fuse 1 because fuse 1 supplies power to both circuits.
Which side of a fuse is positive?
The end that is being supplied with power will be positive if you put a multi-meter across it, and the other end will be cold if you don’t. The hot end will be the same place if you turn it around.
What is the difference between fuse and circuit breaker?
Fuses and circuit breakers are both designed to interrupt the flow of electricity. The fuse works as a piece of metal that melts down when overheated. While a circuit breaker works by operating a switching mechanism when an overflow of electricity is detected.
Does circuit breaker have fuses?
They are found in the circuit breaker box—often referred to as the “fuse box.” Fuses provide a safety mechanism that disconnects electricity supply to a circuit in your home if something goes wrong.
