I have a 200 amp service rated transfer switch. My generator was running for a day and I decided to shut it down to check the oil. I followed the video instructions on the generac website. 1. turn off breaker in transfer switch panel 2. turn off breaker in generator 3. turn off generator from control panel in generator. My question is when I shut the breaker in the transfer switch, there was still power in the house. I'm thinking that when I shut that breaker off, power should have been cut to the house. Don't know if this is proper, or if I have an issue. Any thoughts?

Your house was being powered by the generator until you completed step 2.

The main breaker in service rated transfer equipment serves as the disconnecting means for the utility service entrance conductors.  This disconnect is also ahead of the transfer mechanism.  In an outage, with the transfer mechanism in the generator position, the downstream protected loads are connected to your generator.

What everyone is saying is that the breaker in the transfer switch only cuts the utility power---NOT the generator power (if the generator is running). The breaker in the generator cuts the generator supplied power.
