This diesel generator is designed for standby power. While it can connect to a 100-amp transfer switch, its weight and mobility mean it is generally installed differently than a permanently mounted "home standby" generator. It is recommended to have a professional electrician install it to ensure proper bonding, grounding, and code compliance.
Generac Towable Mobile Diesel Generator, 20kW/19kW, Single Phase, Electric Start, Model# 6028
