SUMMARY

The discussion centers on supplying electric power to two lifts operating at 380 V with a maximum current (iMAX) of 13 A each. The user has selected a 16 mm cable for the main power supply and a 10 mm cable for each lift. The main concern is determining the appropriate size for the main breaker and whether the total current for both lifts can simply be summed to 26 A. It is emphasized that understanding local electrical and building codes is crucial before proceeding with any electrical installations.

PREREQUISITES
  • Understanding of electrical load calculations
  • Familiarity with local electrical and building codes
  • Knowledge of cable sizing standards
  • Basic principles of electrical circuit design
NEXT STEPS
  • Research local electrical codes for lift installations
  • Learn about main breaker sizing guidelines
  • Study cable sizing calculations for parallel loads
  • Explore the role of licensed electricians in electrical projects
USEFUL FOR

This discussion is beneficial for trainee engineers, electrical contractors, and anyone involved in the design and installation of lift electrical systems.

Hey .. !
I hope everyone is doing well.

I'm working on a project and i have to supply electric power to two lifts. Each lift is operated with 380 V and iMAX of something around 13 A. I've selected a cable ( 16mm ) to provide the electric power from the source to the main breaker. Then, a cable ( 10 mm ) will go from the breaker to each lift.

My first question is which size should I use for the main breaker? The second question is, what amount of total current should I provide for both lifts? Can I just add the two currents up and end up with a total current of 26 A?

~ Any help is so appreciated ~

You are asking the wrong kind of questions. You should be asking about local electrical and building codes that specify the legal requirements for wiring, and ask where to find a licensed electrician.

I see, so what requirements are to be specified first?

Actually I'm a trainee engineer. And this is the first task by my supervisor.

Thanks ~
