Client: Uncle Lim, sorry for the last minute request but can you lay wires across from the power supply unit to the outside back balcony of the shop house? I will need 2 isolator for 2 units of system 1.

Uncle: Bought the necessary materials, schedule and worked on both Level 2 and Level 3 and laid the electrical cables with PVC casing all the way into the false ceilings, roof, and back to the back balcony outside and install the isolator in accordance.
