Thanks for your response.
I was reading the AQ Niagara 7000 manual and it says this
"Ideally, the power source to which the Niagara 7000 is connected should be adequate for use at 120V single-phase
nominal voltage, 20 amps (current capacity RMS). However, the Niagara 7000 will operate very well with a 15-amp
service outlet. If the maximum current capacity available is 15 amps, and the system exceeds 15 amps RMS current
capacity, it is possible that there may be nuisance tripping at your electrical service panel. This is not a safety issue;
the electrical panel’s circuit breaker will trip if the maximum current capacity is exceeded.
For proper operation, the Niagara 7000 requires a safety ground (supplied via the power utility AC wall outlet)."
Here is a copy of the manual:

Refer to pages 10-11 for the back of the unit. The receptacle for the AC cord looks like a 20 AMP plug, and that's the only type of cord that will fit (15 amp cord wont fit).
Seems like what you are saying is that the 20 amp cord won't physically fit into the 15 amp outlet on the wall because of the horizontally oriented plug, but according to the manual it says that 15 amp outlets will work.
I'm just confused on how this will work.
