If you plan to use one cord to power two appliances, don't forget to add up the electrical needs of both appliances to make sure that the cord can handle the combined load of power.
What temperature does a wire need to be to dissipate heat?
A wire located in ambient temperature of 50°C (122F) or more loses its ability to dissipate heat, and therefore its ampacity is reduced by 15%. (note: this is per ABYC standards "In Engine Room").
What is the roundtrip length of a wire?
The wire length input is always the round-trip length. The round-trip length is the sum of the positive and the negative wires. Remember that a duplex wire packs the positive and the negative into a single wire, so the round-trip length is equal to twice the duplex length. : 30FT.
What is the term for the amount of current a wire can carry?
Wires can carry a certain amount of current continuously and no more; more current means the wire will overheat (and melt) as it cannot dissipate the heat that is generated by too much current flow. That characteristic is called AMPACITY (maximum current that a wire can carry continuously without exceeding its temperature rating). Certain factors reduce the ampacity rating of wires, and the voltage drop as well:
Why is the max current of a wire running in a van reduced?
This is most likely the case for wire running in ceiling or wall, as it gets much hotter than in the living space of the van (especially for dark color van).The max current that the wire can safely carry is reduced because it has less capacity to dissipate the heat generated by the current flow.
Is an inverter wire dangerous?
