Pro Tip: "upper" coil is SKU / part #G077220
Generac Generator transfer switch generator coil part# 077220A replaces 77220A for 100Amp Generac / Guardian Transfer Switch.
This is the electromagnet coil powered by the generator in Home Stand-by sets.
Note:Order part # 077220 for the utility side coil.
We recommend changing the limit switches # 084464 at the same time as they could have been damaged if the coil shorted out!
