Three most reliable ways to connect wires in a junction box

In our homes, more and more powerful electrical appliances appear: coffee makers, kettles, air conditioners, boilers, etc. All this greatly increases the load on the home network. The first thing that responds to increases in the current of a circuit is wire connections. They are the first to lead to fires if they are not made in an appropriate way. And if there are several of them, and even in a closed junction box, then the total heat released is added up and increased. This means that the junction box is a particularly important and important node in terms of network load capacity.
The three most reliable ways to connect the wires in the junction box
I will tell you three reliable ways to connect the wires in the junction box, which I use myself and recommend to others.

Welding of wires

The first in terms of reliability is wire welding.It is produced by a special welding machine using a graphite or tungsten electrode. In view of the melting of the metal gives the mixing structures and the wires become as one. If possible, use it.
Welding of wires
Pros:
  • The most reliable connection of all presented.
  • Suitable for aluminum and copper wires.
Cons:
  • Requires special equipment.
  • Labor-intensive and not always applicable.

Wire Soldering

The second most reliable method of connecting two or more wires is soldering. It is produced by an ordinary soldering iron using ordinary solder and flux used in radio engineering. This is the most affordable way. First, make a twist of a few centimeters, and then solder it along the entire length.
Solder wires
Pros:
  • Very reliable connection with proper length of soldered twist.
  • Available to most home craftsmen.
Cons:
  • Time consuming and not always applicable.
  • Applicable only to copper wires.

Crimping wires

The third most reliable way is to crimp wires with lugs.In view of its speed and reliability, it is often used by electricians when laying wiring in new homes.
Crimping wires
Pros:
  • Very fast, it takes a minimum of time to create a reliable connection.
  • Suitable for aluminum and copper wires.
Cons:
  • You must have special crimping pliers and lugs.

Conclusion

The usual twist, screw terminals, terminal blocks, caps, clips - in my opinion an electrician with 20 years of experience is not a reliable connection of wires! By reliability, I mean that the connection is able to withstand the same current as the wire itself is designed for the entire period of operation without excessive heating. Of course, I use the VAGO and twist terminals in my work, but I try to do it either in a light one wiring where the maximum current does not exceed 5 Amperes, or in other examples with a low current. Connecting fixtures with such terminals is very convenient and fast, you can't argue here. Now many people will begin to assert to me that VAGOs are very reliable, designed for high currents of 32 A, etc. But my many years of experience, unfortunately,claims the opposite.

And therefore, the three connections listed at the beginning can be used and you don’t have to worry about the consequences in the future.
