Fridays rumination

Johno12345
I have been thinking (yes, smoke has been rising)


I'm not an electrician, but  am in charge of our facility and have a decent knowledge of how things work



Anyway, I want to have some distribution equipment replaced due to the age and condition of it.


I always specify Schneider Acti 9 boards or Powerpact 4 boards


These boards wont require anything bigger than 63a 3ph, so ill be ok with an Acti 9 board, but the total load is likely to be around 200 amps over an 18 way board. I was thinking that sounds a lot to put through a DB as a continuous load, but the website implies that its going to be fine. Is this right? I'm visualising a heating effect etc, so what point do you stop with a DB and go to a panelboard? Usually, if I need to supply something larger than 63a, I know ill need to have a panel board and can budget accordingly


Anyway, as I said, I'm just thinking out loud in preparation for budgeting

    Hi johno, as these are existing dbs when you say the total load is ‘likely’ to be 200amps continuous can you not confirm the loads on site?
