Your full power backup is just for lights – prove me wrong

Since moving into Omaxe Gardenia Floors last month, I've realized something about power backup that builders gloss over. They'll promise 'full backup' but for us, it's just common areas and a couple of light points inside the flat. Meri discovery ye hai ki high-load appliances like ACs, geysers, ya even induction hobs, won't run on generator backup. This means you're still vulnerable during long power cuts. I wish I'd asked about the *actual* KVA allocation per flat on DG before buying. Is this normal across Chandigarh projects, ya kisi ne proper 100% flat backup wala system dekha hai? Kya tips hain iske liye?
