I would like to charge an EV at 10, or even 15A through a GPO that has a power meter attached.

The meter states 5(45)A, and Rated Current (Ib ) 5 A Maximum Rated Current (Imax) 45 A

So, will a lengthy continuous draw of 10A be too much for the meter, or does the 45 max mean that I could theoretically draw 45A continuously without ill effects on the meter?
