The installation is so easy as the product has designed such that it can install easily. Any local electrician in your area can install the stabilizer. Kindly refer to the user guide delivered with the product.
Firstly, keep in mind that the stabilizer has 2 in-built MCBs. One MCB is for an emergency that is changeover MCB. It is always advisable to keep changeover MCB off and use only C-series MCB with stabilizers (mainly C-40 or C-63).
