How are available megawatts calculated in real estate?
For example: property has 1,600 Amp, 480V, 3-phase, 4 wire. Presumably there is a formula to calculate MW, but online calculators don’t seem to acknowledge # of wires.
[{"id": "it9i0ui", "text": "3 or 4 wire doesn't matter for power rating. Three phase vs single phase does. Amps x voltage x square root of three. Approx 1330 kW.\n\nIf you're trying to see if the panel is adequate for a certain load, note that 1600A panel rating is a peak/instantaneous load and the continuous load rating is less (80% IIRC). Also, certain loads such as motors will get less than 1330 kW you have to reduce by the power factor.", "replies": [{"id": "it9jcpc", "text": "Thank you for your help. My team is saying we need 4-6 MW of power, but based on our quick search this seems like a huge load compared to our light manufacturing operation\u2026I\u2019m seeing some properties that have ran huge machinery (such as the specs I showed above, where the prior tenant ran a 15 ton bridge crane). Should I go back to my guys and ask them to re-confirm we need this amount of power, or is 4-6 MW pretty run of the mill?", "replies": [{"id": "it9jvxi", "text": "That's a lot for light manufacturing. Probably they mean kW or forgot to divide by 1000 somewhere in their calc.\n\nFor reference, I have a light manufacturing tenant in 50k sq ft that is fairly energy intensive, electric bill is over $10k/month. They're using a 1200A main panel.\n\nIf you are looking at a Bitcoin mining operation then yeah I've seen those shopped with requirements in the MW range.\n\nEdit - if the load really does add up, then you'd want to evaluate how much of that runs at the same time, are they intermittent or continuous uses etc.", "replies": [], "depth": 3}], "depth": 2}, {"id": "ita3883", "text": "Username checks out", "replies": [], "depth": 2}], "depth": 1}, {"id": "ita6o86", "text": "By electricians", "replies": [], "depth": 1}, {"id": "itag8z1", "text": "There is no way you\u2019re running 4-6MW.
