they use a tricky cable,

00:00:06

not only do they lay it in

00:00:09

their plasterboard houses not in metal

00:00:12

sleeves inside their light structures of

00:00:14

their cardboard houses, but the

00:00:16

cable itself consists of three cores, one of

00:00:19

which without insulation probably

00:00:21

saves correctly Americans know how to

00:00:23

save there is less insulation on everything less

00:00:25

money less cost more profit it turns

00:00:27

out that not everything is so simple,

00:00:29

while in our country hidden electrical wiring on

00:00:31

fire-resistant structures is carried out in

00:00:33

metal sleeves and in metal pipes in

00:00:35

some countries

00:00:37

only metal water pipes

00:00:39

can be installed in a wooden house

00:00:41

without all sorts of metal sleeves and a

00:00:43

corpse inside their houses to lay

00:00:46

this tricky cable marked nkm

00:00:48

this cable has an uninsulated core

00:00:50

which is naturally a

00:00:53

protection ios protective earth how it

00:00:56

works why this wire is not

00:00:58

insulated but it helps to quickly

00:01:01

recognize a short circuit see this

00:01:03

protective wire earth according to e protection from the well-

00:01:06

known in our marking, the yellow-

00:01:09

green wire is simply there without

00:01:10

insulation, if some kind of

00:01:12

short circuit occurs, the insulation of one

00:01:14

of the two insulated wires melts, a

00:01:16

short circuit occurs with this non-

00:01:17

insulated wire p.e. protection is triggered, the

00:01:20

main emphasis of the Americans is

00:01:22

on calculation, selection and installation of the correct

00:01:25

protection devices and in testing and

00:01:27

further precise work, that is, the most

00:01:29

important thing is to protect this network and not

00:01:32

the insulation of the wires, I just don’t need it until the

00:01:34

melting of the insulation of

00:01:36

neighboring wires occurs; we’ve already eaten naked and

00:01:39

in an abnormal mode with this

00:01:41

short circuit, this goal and cue will

00:01:44

quickly close with the burnt other

00:01:47

wires and the protection will work; if

00:01:50

it were insulated, then this thermal

00:01:53

process would take more time

00:01:55

to melt its insulation and

00:01:58

at the same time close and the protection would work, you

00:02:01

understand, yes it’s a different approach, we have

00:02:04

the wire going to the end user,

00:02:07

of course it can also work at the moment there is a

00:02:10

short circuit somewhere in the wiring along its length,

00:02:13

the main thing is fire protection is to

00:02:15

wrap this wire in some kind of pipe in a

00:02:18

sleeve to somehow protect it so that it

00:02:20

heats up surrounding space

00:02:23

such a tricky wire is used when

00:02:25

installing electrical wiring in the USA
