I'm currently designing a control panel requiring a 240VAC 3 phase 4 wire supply (controlling motor loads). Though the majority of the loads will require the 240VAC 3 phase and the control 24VDC, I do need to install a 110VAC receptacle. Can I simply pull that power for the 110VAC receptacle from L1 and Neutral of the main supply (properly fusing it of course),or do I need to install a separate 240VAC to 110VAC transformer? Basically, do I need a separately derived neutral for my 110VAC loads? Appreciate the help.
