You may have read the post about the transfer switch we wired at Zach’s house?
And it’s possible you read the post about the Urban Air Cooled Generator
As fo Feb 21, I’ve done quite a bit of experimenting and we’re close to doing the actual install where we tie all of this together. If you have an electrical or electronic background, you’ll easily follow the wiring scheme. As I had mentioned before, the install is simplified because we only need deliver 120VAC to our transfer switch as there really aren’t any 240 VAC circuits we need to power in this house.
We’ll run three 10 gauge conductors between the generator and the transfer switch and main breaker panel.. (less than 40 foot run) Hot, Neutral, and Ground. Along with those three, we will run a piece of CAT5 in the same plastic conduit for other functions, one will be a battery lead from the 12 volt start battery in the generator cabinet, this is used for three purposes, one is a battery voltage monitor, two is a method to trickle charge the battery, and a third is to activate the relay controlled functions in the cabinet. The run switch at the remote panel activates the fuel valve to open position. The momentary push button activates the motorized decompressor, The momentary start button operates the starter. The decompressor is all about being kind to the starter and making it last longest and assuring we can start the set with a poorly charged battery if necessary. We have spare wires for added functions, but one lead sounds an alarm inside the house to report abnormal conditions, we can also add other functions like over temp, no lube oil pressure and more to shut the fuel off.
Today I added insulation to the cabinet to control noise, and tested the muffler modification. For those of you who remember the Olds 442, you may remember it had no muffler. Instead, Oldsmobile used an exhaust pipe that had accordion like pleats from the exhaust header darned near to the tail pipe. It was fairly quiet at idle. I have a flexible exhaust pipe that screws into a pipe thread exhaust tip-off the stock muffler, the other end goes into a box full of fine mesh screen that acts like a diffuser. Since the pipe is stainless, it should last a lifetime.
Expect pictures and maybe a video or two during installation..
