In a residental home can i install a 14 kw generator (58 amps) to feed the emergency side of a 200 amp ats and have the normal side of the ats being feed with a 200 amps
 
Do you comply with this?

No, 705.5(2)(a). Optional Standby equipment must be capable of carrying the full load of ATS.

Yes, 705.5(2)(b), if you employ a load shed type ATS.
