That discussion should be part of the things you do when you select your electrician.
Personally I will not warrent material and parts purchased by others- even if I would have purchased the exact same thing for that job.
Legal and warrenty issues can be severe headaches despite the best of intentions.
Installing a generator, transfer switch, and all the associated equipment is a job for experienced, licensed, and careful people only. There are too many ways to cause trouble, damage and/or injuies eveh death with one of these setups.
When done correctly you can have years of service from this kind of equipment.
Please talk to your chosen electrician before you buy. He/she may be able to save you money and time.
