I'm starting a rewire soon where the customer has completely gutted the house except for the plaster ceilings. They're installing a drop chicago grid ceiling and attaching drywall to it. I'll be installing the recessed lights. My question is about supporting the romex above the drop ceiling. What is the best way to do this? I was thinking of just stapling the romex to the plaster ceiling but I thought I'd ask if anyone else has experience in this type of scenario. Thanks.
