to answer your question mr. marge, transformers step up or step down volt amps (or wattages). your doorbell uses a step down transformer and converts the 120V input to 12v output that runs the bell.
just so you all know, I am working on it, I dont plan to release it tonight, it will probably be at least tomorrow if not tuesday after work. I decided to do it 100% right from the start, as you can kill yourself.
I am not an electrician. My understanding of a GFCI, it would require GFCI breaker and wiring from the main panel to be a 'true' GFCI Circuit. I have been wrong before, I just want you safe. VV
No the actual breaker is not a GFCI. A gfci breaker has a trip switch on it, mine is yellow, you can easily indentify which one it is. It also costs about $30.00 for the 20 amp size compared to less than $5.00 for a regular 20 amp breaker. I still think the gfci receptacles trip faster in any case. I installed one, I was told it was necessary to meet code and since I was doing all of the work myself not meeting code would have been putting my friendly electrician's license at risk. He pulled the permit for the job, meet the electrical inspector at my house to discuss the work ahead of time. I paid him what he asked, $100.00. He had to pay $35.00 for the permit. He never asked for the money until after final inspection and approval. I am done discussing this issue. VV
Are you saying you just did this? If so.. got pix? I'm weird, I like to take pictures of things I've done. For instance, I have pictures on my computer of every computer I've built. I have a HUGE folder dedicated to my bike. To my plants (I have folders on ALL of my computers for my garden )... Ok, I'm weird.
