Fluorescent & HPS fixtures on same circuit


Can fluorescent fixtures (2 lamp 32w T8) and 150 watt single lamp HPS fixtures share the same circuit? Any issues with harmonics? Both types are 120 volts.

Thank you,
Mike

1) yes
2) possible, but only on wye connected 3 phase systems ... but irrelevant whether they share the circuit or not

To answer your first question yes it done very often as long the total load do not excessed the circuit conductor size requirement.

Second question it only affect on triphase supply not affet with single phase supply { unless you got serious unbalanced load }

Merci,Marc
