The simplest solution to the problem of overloading a particular outlet with an extension cord connected to it - the usual mechanical interlock.
The essence of this method - the power of consumers is made through an extension cord with a limited number of sockets sockets, which is chosen individually based on the location socket arrangement.
The implementation of this method is facilitated by the fact that commercially available multi-port extension cords designed for the connection of two to six different devices.
For example, Figure 1 and 2 (below the gallery) extenders are shown with three slots and six rosette.
Determining the number of extension sockets is as follows.
6-ampere outlet maximum total power of the connected loads should not be old-fashioned exceed 1380 watts, and at the transition to the new socket with the limiting current of 10 A, this parameter is limited to 2.3 kW.
To select a specific outlet device which has the highest power, for example, 0.8 kW.
Assuming other consumers 250-watt, total extension sockets for our example found as (1.38 - 0.8) / 0.25 + 1 = 3 socket. Rounding to the nearest integer below (e.g., 3.75 accept outlet calculated in 3) creates margin in the calculation.
When choosing an extension cord, ceteris paribus it is advisable to dwell on the model, which in addition to the switch with backlight has a built-in fuse.
Last relieves stress from all the socket when the current exceeds a certain threshold value.
