So to sum up, a fuse is a one time protection device that interrupts a circuit. A relay is a device controlled by another part of the circuit and operated to connect or interrupt the circuit many times.
Where is the fuse box relay?
It is usually a large rectangular plastic box with a removable cover. If you can't find it, refer to your vehicle owners manual for its location. This is what you'll find inside the power center when you open the lid. The fuses and relays are often identified inside the power center cover.
Where should a fuse be placed in a circuit?
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.
Where does the fuse go?
The fuses are placed in the positive lines from the battery and close to the battery. If a fault occurs on the line between the fuse and the load the fuse blows and current flow stops.

What is a relay box in a car?
In the fuse box on a modern car, you'll find a whole bunch of multi-colored electrical fuseselectrical fusesIn electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.https://en.wikipedia.org › wiki › Fuse_(electrical)Fuse (electrical) - Wikipedia and larger, plastic boxes called relays. ...
