What harm does AC contactor coil wire loose have? If the wire connecting the coil is in poor contact, there will be two cases. The first one is that the AC contactor does not act. Because the wire is in poor contact, it is likely to be disconnected, and the current cannot pass through the coil. The AC contactor will not work.

In the second case, the AC contactor ignites, because the wire head is loose and the contact is poor, and the voltage of the AC contactor is unstable, the back and forth action of the ignition will occur.

The consequence of AC contactor coil wire loose is very dangerous, because AC contactor is the control electrical appliances, so it is likely to move back and forth, which will damage the load.

The contact wire of AC contactor is loose

If the contact wire is loose, just as the subject said, directly burn the contact and melt it, because the loose end of the wire will make the wire hot and hot, and may ignite, thus burning the AC contactor.

Harm of bad contact of thread ends

Poor contact is a major problem in the use of electrical appliances, but also the culprit of many accidents, whether it is wire to wire, or poor contact between wire and electrical equipment, will cause electrical fire, the following analysis of the reasons.

If the wires are not in good contact, they will form an arc and spark at the contact point. Sometimes when you turn on the light or plug in the socket in the home circuit, you may find that there is a spark, which may be the cause of poor contact. The best way is to remove the wires to see if they are loose.

If there is poor contact between the wire and electrical appliances, the resistance of the wire will increase, which will make the wire hot and melt the surrounding plastic shell. This is also the reason why some electrical appliances have dark hair and soft hair, or the plug can not be pulled out.

So before the power on, we must make sure that the connection is correct, and all the wires are tight, in this state, we can carry out the next test.
