fan installation industrial

just received this question on a college coursework and dont know how to do it please could you help just wondering on cable sizing and breaker sizing . its 5x industrial ceiling fans ratings for the fans are as follows VOLTAGE 230v,WATTS FULL SPEED 67 watt,FLC Amps 0.30amp per fan which i have 5 fans on the same circuit all the cable run is 100 meters clipped on a cable tray bunched im just wondering on the cable sizing and the breaker size and type which should be used. l thanks if you could help with any information

Personally i would run in a 2.5mm cable with a seperate FCU for each fan fused down to 3A.
For MCB you could go for a 10A or a 16A.

thanks for the reply much appreciated what type breaker would it be a,b,c type breaker thanks if you could reply back cheers pal

B.

You will still have so much overhead in a 10A breaker to cover any initial startup surge.

 

[mars6394]

would you suggest a 16 amp type b breaker then

Hi.

If this is a college question wont they want to see how you arrived at the cable size and breaker rating etc???

Yep, sounds like a design question to me.

 

[pmac10]

as its an industrial setting you would use a c breaker, b breakers are for domestic use

I'm learning about cable factoring and design currents and things at the minute.just would like to know correct type of breaker size eithe 16amp or a 10amp type b or c.I will jst write answer down sod the working out lol .thanks for replys people jst need size and type breaker thanks

 

[pmac10]

6 amp type c( all fans running at once is only 1.5 amp) and prob 2.5mm conductors, if you cant be bothered workin out voltage drop neither can i, this answer should do the trick, just hope you dont have to explain yourself,
good luck m8.

 

[mars6394]

Would it be a 6 amp or a 16 amp breaker

 

[pmac10]

six, you could go lower but SIX.

 

[mars6394]

breaker depends on loading cable depends on loading maximum zs for that breaker probley a c type for induction motors like fans also volt drop must be taken into account
