You often leads melt because the wires are too small (For small cross-section mm2). When it comes to dimensioning 12 volt wires / fuses must focus on duct cross section which reflects, how much power (Amp) that can be transported without, the cord gets hot and thus a risk of fire.
Apply one thin wires is lost energy which can also lead to risk of fire. Tube lengths are important for any. power loss, The longer leads are, the more power loss. There must leding and security be correctly dimensioned, in order to avoid power loss and avoid the risk of fire.
Wires are of different cross-sectional, and the larger the cross-section is expensive conduits. You can get wires as single wire as well as double wire.
The battery capacity is measured in ampere-hours (Ah). For example, you use power from your caravan 4 x light of 10 W (40W) + div. 8W = 48W. The 48W divided by voltage which is 12 Volt (12V) = 4 Ampere hour. You can calculate the power consumption of other devices in the same way. If you use such 4 x light of 10 W (40W) + div. 8W = 48W and 5 hours, the consumption of the battery 20 Amperetimer. Your battery max capacity can be calculated as follows for example 75 Amp battery divided by the voltage which is 12 Volt (12V) = 900 Ampere hours. Read more about the battery menu batteries.
Calculation of the wire dimension (section mm2):
You must first figure out your length of the cord and power / consumption (watt). We are based in the above equation (48W), in the example below you can see, at de 48 watt which provides current of 4 A (48W/12V= 4A), and a wire length of 10 meters line frames in the diagram area, where the duct cross section should be 2,5 mm2.
You should be aware of, the wire length is the total length (length x2), Therefore, you must include both wires to the fuse box and minus connection (For example, giving it a total cable length of 5 m).
Please also note, that the theoretical effect of all things strømbrugene, connected to the electric circuit you dimensions from, and must be put together before the wire cross section is read.
What size fuse you should use:
You can in the table below see which fuse sturgeon else you should apply, Once you have found out which wire you need (Wire cross section mm2):
NB. A good advice is, to check its wires 12 volt inverter is properly fixed in the lugs m.v. and that the cable shoe is clamped.
Have been exposed to, that the lugs had loosened, Remember also to check the battery if you have a battery in the caravan. Loose wires / terminals could ultimately create a fire due to overheating where the cord is loose.
