Also recommend transfer switch, installed by Licensed Electrician to not only to provide ultimate safety for the installer, but also give peace of mind that it is done to perform in a safe manner when needed. A true transfer switch "cuts" the energy before the main panel disconnect, on the HELCO side, or un-fuse protected raw electrical side, ensuring complete disconnect from HELCO before introducing electrical current from your generator, and complete disconnect from gen when switching back to HELCO.
I have seen "home made" back feeding into the panel, with the use of shutting the main switch off, then starting generator, and switching circuit breaker infeed on. I have also seen the results of this system gone wrong, where user forgot series of breaker and sent double voltage through, arc flash resulted, evaporating him, blowing a whole in the wall and fire where the main panel was. Not pretty.
