I have a quote - it is really expensive to convert from 1 phase to 3 phase

especially if one hardly exceed the load factor.
Please give you comments..

1) To supply & install 25mm armoured cable from meter board to TNB pole..hacking and premix back.. rm5500
2) To supply & install 16mm armoured cable from TNB meter to DB box - rm2500
3) Supply and install 3 phase DB box with 60 amp ELCB,60amp main fuse and 32 MCB - rm1500
4)TNB meter submission form - rm1200

I know that item 4 , I can already do myself.

also item 1, looks damn expensive..I already hacked my front yard already--where got hacking charges?
