Voltage Meter mounting location

Hello,

I have a portable generator that I use for emergency backup wired into my breaker panel.

I would like to install two meters into my breaker panel cover that will monitor voltage, Hz and watts for L1 and L2 from the generator. See attached photo of proposed location.

My question is if I mount the meters in the proposed location will I be violating any codes?

Any information/suggestions would be greatly appreciated



Please help.

Thanks

I didn't find the right solution from the Internet.
