ගෙදරකට Single Phase vs 3 Phase ගන්න එකේ වාසි අවාසි මොනාද?

[tharakaf]

ube purpose eka light bill eka gewal dekema wena wenama adu kara ganna nam gewal 2kema 5Kw 2k gahapan, CEB net accounting over 5KW+ gahanna be.
investment plan ekak widihata yanne nam 20kw net plus ekak gahapan. 10kw 2k gahana eka terumak ne.


Pacha daanna epa yako. Ranilge kaalema net accounting 5KW walata restrict kare. Mun kare net++ eka ain karapu eka.

යට තට්ටුවෙ කාමර 2යි, උඩ එකේ කාමර 3යි. යට එකට single අරන් උඩ එකට 3phase ගත්තානම් හරි වගේ නේ. වහල 1500sqft තියෙනවා, මම බැලුවෙ ගෙවල් දෙකට 10kw ගානෙ බෙදලා දෙන්න

ඉස්සර ඉඳන් 5KW - CEB, 6/7KW Leco limit එක තියෙන්නේ single phase 30A එකට දෙන්න පුළුවන් උපරිම ගාන නිසා .
ගෙදරට three phase 30 A - 20KW, 60A - 42KW උපරිම ගහන්න පුළුවන් මෝඩ ජෙපි ආණ්ඩුව එන්න කලින් net accounting. දැන් restriction දාලා approval දෙන්නේ නැහැ 5KW වඩා.

We have 3Φ power too.. But AFAIK anything more than 30A single phase or three phase used to fall under bulk supply category. Not sure whether these have changed recently but check.
