absorption on 5 pole plug

[Davimont]

I immediately press that I am not an electrician but that I only have to make a maximum calculation to communicate in the first battura the absorptions present on the supply line of our plants.
I hypothesize a situation to make the idea better.
1 4kw three-phase electroventilator
15 neon lamps with 2 58watt tubes on each stage.
of course 5 poles 3p+n+t

do you recommend a formula to know how much the plug should be to install? Forgive me, but I'm not in the electric field.

Hi.
you need to know the absorption of the various users.
then applying the formula (for current alt.trif) p = i x v x cosfi x root of three ti calculates the absorptions

thanks new rider
but if you want to make an approximate account just to know where to start, can I assume for the engine a double absorption of its power? for the lights the classic watt/v formulin can go well?
for the previous example I would do 8a for the motor and 7,6a for the lights. total 15.6a total. I'll get him a 32nd.
I know it's salami accounts, but it's right not to mount a 16th undersized or a 63rd unnecessarily.

Approximate accounts do not. Fire everything. also attention to the section of the power cord of the socket.

You're right to say that approximate accounts don't happen but in my case there's no nuclear power plant. I have an aspirator and no lights to feed. If by doing two accounts I get a 10/11a absorption I can mount a 16a. If I come out 14th then I give him a 32th.
then the same data I pass them to the quadrist to do just the picture with motor ignition and three switches for the lights. If something doesn't come back, he'll warn me.
Depending on the socket, the cables of adequate section are installed to prevent excessive overheating and subsequent fires.
Anyway I try to apply the formula you kindly wrote me over and see what comes out. Meanwhile thank you for the advice.

the calculations are correct, but it seems to me that for these installations it is necessary a project signed by a member to the register.

 

[Davimont]

exxon this I don't know how to tell you and maybe I'll ask upstairs. I'm just an employee pulling 4 lines on a screen and trying to do his job best.
I know that when we pass the order to the outside company to make us the electric square the project of the same is released.

You're a mess
blower and lighting together on the same line?
Don't do it.
First of all there is that the fan has a plug, but it is not obligatory, and there is therefore a socket,
but the lighting that has a plug did not know, except in the yards
the line of lighting arrives at the picture where there will be its beautiful interuttore,
also the fan can have his line coming to the picture with his handsome switch
then say "obviously taken 5 poles 3p+n+t" is not said depends whether the transformation booth is user or enel
if the user is the power supply will be 3p+n+t with ground system in the cabin,
if it is not of the user will be 3p+n with ground plant around the building
for the line you have to calculate the voltage drop, in value and in percentage
There are a lot of things to do, are you the one that should size the switch? We hope not

Then it ended? ? ?
which made three monophase lines for lighting

 

[Davimont]

Blower and lighting is often done in my case. our product is to all effects a mobile cabin with aspiring machine and internal lighting that I can move from one place to another.
on the back of the car the picture (made from external company) powered by a plug. If you put one plug or two separate, the customer tells me that according to his preferences.
when the customer places the car in his shed or in the yard will only have to get him a cable with adequate grip and can work.
the fact of asking for lumen only on the 5 pole plug is because if I have to manage two separate thorns (one for the 400v and one for the 230v) then I already know how to dimension them. I do not understand how to calculate the load when I have a single 5 pole plug where I have to divide the load of the lights (230v) on the individual steps to not have an excessive imbalance on one of them.

Then it ended? ? ?

It didn't end a way because the question was just informative, I wanted information to better understand how to deal with it.

No, I don't size the switch but I have to give a starting value. If they sing it great, the catheter thinks of me as a cicchetto

ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
I think it is a good thing to do.
This post is Mooooooooooolto more precise than the first,you will
it seemed you had to put a fan on the ceiling and light the stand
the power supply is external to the cabin and it happens through the plug that connects to the external socket of the cabin that feeds the inside of the cabin, which picture will have a three-phase switch for the fan and three single-phase switches, for each different phase, for every five lamps

!!! :d
I apologize for the initial inaccuracies.
