Amperage is a measure of
the electrical current flowing through a circuit.
Current is measured in amperes or "amps". You must use
the correct size wire for the amperage requirement of
the circuit to prevent the wire from over heating.
-
The number and type of
electrical devices connected to a circuit determine the
amperage requirement of the circuit. Usually, a general
purpose house circuit is designed for 20 amps. Lighting
circuits may be designed for only 15 amps.
-
To calculate the amperage
for a circuit, first add up the wattage of all the
electrical devices that will be on the circuit. Then,
divide the total wattage by the voltage of the system,
110 or 220, and that will give you the expected current
or amps.

WARNING!
Installation of electrical wire can be hazardous, if done
improperly, can result in personal injury or property
damage. For safe wiring practices, consult the National
Electrical Code® and your local building inspector.

RG59 Siamese Cable: is more heavily shielded so it's more durable and can be run longer distances (up to 1000 ft. without a repeater).
It's heavier shielding makes it less susceptible to interference. Florescent lighting in particular can interfere with camera signals.
The RG59 is purchased in 500 or 1000 ft. rolls and each camera run is cut to the exact length needed. Since you need to cut the cable and attached the connectors,
it is a little more involved to install. 500FT approx. $150.00 |
