Rating between power cord and equipment
Mains equipment and power sockets are usually rated in amps (A) rather than milliamps (mA) - so I would assume that:


The equipment requires 5&nbsp;A
The socket can supply up to 15&nbsp;A (although this (at least in Europe) is usually 13&nbsp;A)


Regardless of this, the socket will only supply the current that is required. So your equipment only requires a third of the current that the socket is able to supply - so there is no problem in that respect.

If it situation was reversed, and your equipment needed 15&nbsp;A and the socket could only supply 5&nbsp;A, then there would be a problem, and the equipment would not be able to function correctly, or overload the socket.



When matching devices and power supplies Just remember: Voltages need to be matched, whereas current drain needs to be less than the supply.

In other words:


If the current capacity is greater than that required by the device, this is not a problem.
If the voltage of the supply is greater than that required by the device, then that will probably fry the device.
