But, please keep in mind that if you were to try and use the unit with a transfer switch for home back-up in 220 mode you would have only 15 amps MAX for each of two branch circuits.
Yea that's why the 46514 is attractive. I'm sure that I can run the things I need in 220 mode, but I'm not positive that I can start them. I'm going to start with properly sized extension cords for emergency use and once I know what works, I can add a transfer switch.professor95 wrote:
The 46514 is better suited for backup operation by connecting to a breakout box via the single 30 amp 120 VAC outlet or splitting the 220 volt outlet via a different style breakout box into two 15 amp circuits.
By breakout box you are referring to one of these transfer switches that connects as a sub-panel right?
I have one other question to ask. Hopefully it's relevant enough in this thread....
All the emergency items (sump, refrigerator, lights, etc.) can be powered by removing the plug from the wall and the device being powered is isolated from the house circuits. Since I'm going to hold off on the transfer switch for the time being, I needed to add a plug to my direct connected 120V heater blower motor. I added an outlet connection to enable this. On thing I noticed is that, even with the blower motor disconnected, there's still continuity on the round ground plug for the blower to the newly installed metal outlet box.
Even with a transfer switch the ground from the electrical system is still connected to everything in your house, in other words the transfer switch does not open the ground, just the hot wires
At first, this alarmed me. After thinking about it, I decided that the 220V AC unit was another source of ground for the blower unit since there's a metal connection between the two (copper coolant pipes).
This also means that when the generator is plugged in to the heater blower, its green wire ground is connected to the house wiring and therefore it's also bonded to the common wire via the main breaker panel.
Does this impact how the generator is configured when used for emergency backup and would it be different depending on whether it's connected to the blower motor?
