How do we choose a circuit breaker? a single phase or 3 phase? If i were to install one for a router?How?

Answer 1

Wire the router direct to your mainline incoming power and baby you can make ALL the right moves on the dance floor.

Answer 2

you need a normal  110 volts to run a router ..

  single phase   only .... it a good idea to only run this machine by it self . as its has a motor built in ....

     so u need a 20 amp breacker    110 volts

  

  ignore the other answers  they unhelpfull  almost insulting

Answer 3

If you don't know, you shouldn't be messing with it,

but, In the U.S.:

1. Look at the nameplate on the router.

It will give you voltage and ampere draw and/or Watts.

If the voltage is 120. You need a single pole breaker.

If it's 240, you need a two pole breaker.

(You won't need a 3 pole unless it's a very large machine, and any place with 3 phase power will have a maintenance staff to do this for you.)

The ampere load will determine the trip rating of your breaker, and the wire size needed.

There are simply too many ways to s***w up and hurt yourself or start a fire trying to do this job.

Hire a pro.
