Electrical Question: Do I have enough power for my portable AC units



Question:
I'm working with some portable air conditioner air conditioner units and each requires 1 Phase, 208/230V, 20amp.

I have (4) units total. I'm bringing these to a venue that can provide 200amp 3-phase power.

The venue has told me to bring in my own 208v distribution box with compatible NEMA connectors.

My question is - is this enough power to support the (4) portable air conditioner air conditioner units??

Yes - The 3 Phase 200 Amp power is more than enough to supply for you're air conditioner air conditioner units. Special attention will be required to make the correct connections between your power units and the 3 Phase supply.
As they have mentioned, the right NEMA Connectors will be required, Male and Female, with matching voltage and amperage configurations.

 

You may want to ask the location if they have an on-site electrician that can assist you, otherwise it would be wise to locate one to make sure the connections are correct and allow time in case the electrician needs to make a trip to the supply house to get the appropriate connectors, cords etc.

Be Careful and Be Safe - Never Work on Energized Circuits!

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
