Why does my CB keep blowing fuses?

Why does my CB keep blowing fuses?

If the fuse keeps blowing, you have a problem. A high VSWR could cause the problem if the finals of the CB are seeing a higher than normal voltage across them and are dissipating more power than designed for. Check your VSWR just to be sure.

What fuse should I use for CB radio?

What size fuse for the -? Thanks. 15 to 20 is good. As long as the CB isn’t modified it should put out 4 watts.

Why is my CB radio not transmitting?

Make sure the connections are tightened. Ensure that the microphone pins on the radio are making a connection with the microphone plug. Be sure you are pressing the CB microphone button all the way in. If it is a power mic or echo mic, make sure there is a battery in it!

What size fuse does a CB radio use?

Most aftermarket CB power cords have a 4amp fuse.

How many amps does a CB radio draw?

Actually, it states 0.3 amps (300 ma) squelched, and up to 1.2 amps with full audio output.

What is a CB fuse?

The idea of a circuit breaker or fuse is to disconnect your home’s internal circuit from the power main when excessive voltage tries to pass through. The main purpose of a circuit breaker is to protect your home and its electrical components from an electrical surge.

Do CB antennas go bad?

The antennas do not actually ever “go bad” however just like everything they are susceptible to water damage. If yours is sealed and has no signs of corrosion it will be fine. All that is inside of them is a wire of the proper wave length, keep it dry and it will last forever.

Are CB amplifiers illegal?

Although the commission has eliminated many citizens band rules, such as the requirement that CB operators be licensed, it still strictly enforces the ban on so-called linear amplifiers, which can increase the power of a CB signal from the authorized 4 watts to several hundred watts.

How many amps does a radio use?

A typical stereo head unit will need about 5 amps of power. If you want to crank up the volume for parties and plan on using a powerful amplifier, then 5 amps likely won’t be enough either. We do have power supplies available that offer up to 30 amps. Some people will use computer power supplies and they work great.

Which is better fuse or breaker?

Fuses trip faster than a circuit breaker. Fuses are initially less expensive than circuit breakers. Because a fuse is replaced every time after an overcurrent trip, the same level of circuit protection performance is guaranteed. A circuit breaker can wear out if it trips too many times.

What is the difference between CB and fuse?

The main difference between the two is that a circuit breaker can be reset and used over and over again while a fuse is a one shot deal that has to be replaced. A fuse can be improperly replaced with one rated at a higher voltage that may result in an overheated circuit.
