How long will a direct aluminum-copper connection (twist) last

Valentine asks:

Hello. This means panic, I know that a metal adapter is needed to connect aluminum wiring with copper, for example brass. Well, or many other ways.

The question is, I live in the wilderness, I won't get to the market soon. And while he twisted the light bulb in the kitchenette into a straight line. That is, I attached copper wire to the old aluminum wiring by means of ordinary twisting.

Question: How much a given skill, in such a state, can work, without the manifestation of unpleasant consequences due to the combination of such metals. Let's say, a period of two weeks, with the robot light bulbs within 12 hours a day, until the moment when I can get adapters, well, or something else?

Hello! It all depends on humidity, load (you have a small one, a light bulb, you write), temperature conditions of the environment.

Take two ordinary bolts, which is convenient, well, M4-M8, each with a nut and 3 washers for each (6 in total). Take the bolt, put the washer under the head, then fold the veins into a ring, first put one on the bolt, so that the ring is twisted as if to the side tightening the bolt, then put on the second washer and the second core, here the ring should be twisted in the direction of tightening the nut so that when tightening it does not untwisted. After that, one more washer and tighten everything with a nut from above. Do not overtighten or pinch and cut the aluminum conductor. Well, wrap everything up with electrical tape.

If you do not find so many washers, then leave at least one between the veins, but when tightening, control so that under the nut in the thread does not jam the core and does not damage it, so that it is firmly pressed by the nut, and the second core - with the head bolt!

Then you can sleep well if the connections are made well.
