Newer homes built in the US are more efficient and don't require amperage like the in the past. That's why you see 100 AMP service for a normal size 3 bedroom 2 bath house now. My house was built in the year 2000, which is considered new in the housing world and came with 100amp service. If the house was 20 years old, I bet it would have 200-300 amp panel in the basement.

FWIW I have never seen a 300A panel in a home. 200A is the highest I've come across and that's usually in McMansions. Standard is 100A, and I've seen much, much older homes at 60A.

2000 watts(approxomate Neptune draw) / 110v = 18 amps per Neptune. (USA)
5 Neptunes would Max-out 100 amp service right there
Some of us installed 200 amp months ago.... Then, lightning struck... literally

That would be 100 amp service at 240V. You have two 120V phases coming into your house each at 100A. Five Neptunes is a lot; but, you make sure your running 3 on one phase and two on the other.

Yes, I agree... also if you use 220v to supply your Neptune, the amps will be 50% less, while the Wattage remains unchanged.
