The mobile cable should not exceed 10-15 meters in caravan feeders.
The contact feet of some low-quality sockets are non-standard.
In sockets with non-standard metal contact feet structure, it is inevitable to scorch due to heating at these points due to the high conductivity resistance.
Resistive punctures are more dangerous than short circuits in electricity.
The mobile cable used in the caravan should be such that it can be directly connected to the caravan.
A second mobile structure should not be used. Each port creates a resistor.
The mobile cable to be used in the caravan has a special structure for the caravan.
Its physical structure should be protected against water ingress.
The plug to be plugged into the place where the energy will be taken should be male, and the plug on the side of the caravan should be female.
It’s not a socket on the caravan wall, it’s a male plug.
It must be a lockable structure when the mobile connection is made.
Being locked prevents children from pulling the plug.
That is why it is so important that the electrical ends of the plug pulled from the caravan wall are buried, that is, hidden.
Some of the caravan builders use home-style table sockets on the caravan wall.
This is a huge mistake, it is open to danger.
There should be no fuses with a current of more than 16 A in the network table where energy is supplied with a mobile cable.
Grounding must be absolutely necessary, otherwise mains energy should not be used.

The thought that the cable is insufficient, must be a thick cable is wrong.
Plug and play Portable cables should not be more than 3×2.5 mm2 cables.
If it is necessary to use mobile on 3 x 2.5 mm2 cable cross-section, that is, 3 x 4 mm2 or more,
According to the internal regulations of the installation, it is necessary to make a fixed connection instead of Plug and Play.

It is a mistake to heat the caravan with a plug-and-play mobile cable over the mains.
2000w kettle should be used, 2000W space heater should not be used out of control due to its long-term and uncontrolled working nature.
No more than 2 KW (2000w) of energy should be drawn from the sockets from which the caravan is energized.
Mobile cables should not be used with fixed installation logic as in homes.
It is important that the Portable Cables are 10-15 meters long and protected with 16 A fuses.
The 16 A fuse is considered to protect the receiver, but to protect the cable.
Especially in caravans, separate fuses should be used according to the current value of each buyer.
When the length of the mobile cable is 40-50 meters, I think the load to be connected to it will fall in the range of 800-1000w. The fuse to be used will fall in the range of 6-10 A.
That’s the problem.
The idea that we can increase the cable thickness and draw as much energy as we want from the network to the caravan is wrong.
What will happen to the in-caravan electrical installation when the cable cross-section is increased here?
Is it a matter of the thickness of the mobile cable, or is it necessary to reconsider the consumption?
