| Make sure you have the right wire size connected to your CB radio equipment, and make sure that wire run is properly fused with an amperage rating no more than the wire's amp carrying capacity. On a 12 volt line to the CB radio transceiver, use 12 or 14 gauge wire, then run it to the battery terminal in order to avoid CB radio equipment interfering with the automobile's system electronic equipment, and make sure you have a inline fuse holder on your CB radio power cord with a fuse with an amperage rating no more than 4 amps, or no more than the fuse amperage rating that CB radio equipment call for. Do not over-fuse the CB radio equipment no more than 1.5 times the CB radio equipment's maximum current drain.

!Warning!
In order to be safe to avoid any fire hazard, make sure that fuse or circuit breaker is connected near the electrical power source or the battery with a fuse or circuit breaker amperage rating no more than the wire size maximum amperage rating of the wire run, and make sure you have a inline fuse holder on your CB radio power cord with a fuse with an amperage rating no more than 4 amps, or no more than the fuse amperage rating that CB radio equipment call for. So be safe, and not sorry.

Here is this quick reference wire size chart:
| If you are not sure about wire size and the amperage, consult an electrical expert; or if you are still in doubt about the consultant, get a 2nd or 3rd opinion from another electrical expert. So be safe, not sorry. |
When wire size is larger than 0000 gauge, the wire is measured in MCM:
| Table Of Definition |
| d = |
Wire diameter in mils (1 mil = 0.001 inch or 1 inch = 1000 mils) |
| MCM = |
1000 circular mils |
| circular mils = |
d² |
| d = |
sqrt (circular mils) |
Here is the MCM formula to convert wire diameter in mils to MCM:
MCM = d² / 1000
Here is the MCM formula to convert wire diameter in mils to MCM:
d = sqrt (MCM × 1000)
