3Phase Machine 1 Mcb

[thewiz]

Hi all, now I know this is not the correct way to install this but bare with me.

One 3 phase 20amp machine has been installed

Been asked to install another, one problem... Needs a larger db to fit the new 20amp machine but they need it working tomorrow.

For short term use do u think I could double up on the 20a mcb? The machine will not be ran at the same time as one person will be working on them and can't use both together?

fit a changeover switch,

and all is good in crinklybottom wood once more,

My Lathe & Milling Machine share the same TP MCB.

It's only me that will run them, & sometimes I put a cut on the miller, then do some turning, no worries.

If the MCB trips, it's my tough luck.

Mind of the two of them get above 10A combined I'll be amazed!!!

Nothing wrong with a change-over switch though.

Changing the existing breaker to a larger size that feeds an additional board may be better. Even the existing breaker may be able to be reused in the new board.
