Add the Amplify power management system (see below) for whole house power management. The Briggs & Stratton 40677 includes Dual 200 Amp/Split 400 Amp Automatic Transfer Switch for installation on a 300 Amp or 400 Amp split service with two panels. PowerProtect Series generators install just 18 inches from your home, taking up less space and fitting into your landscape. More powerful than competing 20kW generators, Briggs and Stratton rates the air-cooled standby at 20kW for LP Propane and 20kW for Natural Gas. ![]() PowerProtect Series generators have a sleek, neighborhood-friendly design and feature tool-less accessibility to all major components for routine maintenance. The 40677 has the longest, most comprehensive standard warranty in the industry. Adjustable time delay to override momentary normal source outages to delay all transfer switch and engine-starting signals.Briggs & Stratton’s newest 20kW Standby Generator is the most powerful 20kW in its class.Unloaded running time delay for engine cool down – adjustable 0 to 60 minutes (Feature 2E) Pre and post signal time delay for selective load disconnect with a programmable bypass on source failures – adjustable0 to 5 minutes (specify ASCO Optional accessory 31Z).Re-transfer to normal time delay – adjustable 0 to 10 hours (Feature 3A).Emergency source stabilization time delay to ignore momentary transients during initial generator set loading – adjustable 0 to 4 seconds (Feature 1F).Transfer to emergency time delay – adjustable 0 to 60 minutes (Feature 2B).Engine start time delay – delays engine starting signal to override momentary normal source outages – adjustable to 0 to 6 seconds (Feature 1C).Remote time delay bypass switch emergency to normal.If emergency source fails, switch will automatically transfer back to normal source if acceptable. Remote contact for test or for peak shaving applications.E-mail capability for system events, including e-mail to SMS text messaging.Built in web server, with full display and control capabilities.Selecting settings : single or three phase voltage sensing on normal, and single phase sensing on emergency 50 or 60 Hz.Voltage and Frequency parameters adjustable in 1% increments. ![]() ![]() True RMS Voltage Sensing with +/-1% accuracy Frequency Sensing Accuracy is +/- 0.1Hz.Under and over frequency settings on normal and emergency sources.Three phase under and over voltage settings on normal and emergency sources.Three – phase/single - phase selectable switch. Selective load disconnect control contacts (two provided) which operate with time delay prior to and/or after load transfer and re-transfer.Engine exerciser to automatically test backup generator each week-with or without load for 20 minutes.Inphase monitor to transfer motor loads, without any intentional off time, to prevent inrush currents from exceeding normal starting levels.Easy to navigate 128圆4 graphical LCD display with keypad provides LED indicators for switch position, source availability, not in auto, and alert condition. ![]()
