I guess "electrically speaking" it would work. However, you now have to face the fact that the whip that comes out of the bottom of the Reliance unit has to go into one panel or the other. Once you choose a panel you can't just nipple into the other and split up the circuits. You're better off using that Reliance unit for one family and one or two of these with extension cords for the other.

I thought this forum would be a little more helpful and courteous, i did not expect one word replies like yes.

Sorry for the rude welcome-sometimes things come accoss wrong.
I don't think this is compliant because you can't have neutral conductors not originating in the same panel as the line conductor. This problem is similar to the situation of using 1 ATS for 2 different services which would require a switched neutral.

Thank you,next time i won't be so sensitive.
If you were offended then I apologize. Now, to your OP. I see several problems IF you have what I think you have. Do you have a duplex with 1 service feeding a 2 stack meter base? Are they going to use a portable generator smaller than 15 Kw? If the answer is yes then here are your problems. A portable generator connected to the premise wiring must be connected as a separately derived system, switching the neutral. From the UL white book
ENGINE GENERATORS FOR PORTABLE USE (FTCN)

GENERAL

This category covers internal-combustion-engine-driven generators rated
15 kW or less, 250 V or less, which are provided only with receptacle outlets
for the ac output circuits. The generators may incorporate alternating or
direct-current generator sections for supplying energy to battery charging
circuits.

When a portable generator is used to supply a building wiring system:
1. The generator is considered a separately derived system in accordance
with ANSI/NFPA 70, ??National Electrical Code?? (NEC).

2. The generator is intended to be connected through permanently
installed Listed transfer equipment that switches all conductors other
than the equipment grounding conductor.

3. The frame of a Listed generator is connected to the equipment grounding
conductor and the grounded (neutral) conductor of the
generator. When properly connected to a premises or structure, the
portable generator will be connected to the premises or structure
grounding electrode for its ground reference.

4. Portable generators used other than to power building structures are
intended to be connected to ground in accordance with the NEC.
If you are under the 2011 you may all so run into problems with 406.4 (D)(4). Code aside there may be problems with who is responsible for the generator, fuel, upkeep. What if one doesn't pay the power bill and gets the meter booted are they going to run the generator until they get things taken care of?
