Total cost is under $20.
This works for the initial check, something I will still do, you are correct there. What happens when/if the voltage spikes or drops or someone else draws a lot of amps and now you don't have enough for your needs on the second day of being hooked up? Or you are outside using an outlet and can't see the meter mounted inside? I installed an EMS and was happy to pay for the insurance of not having issues. In the event I do, nothing will get damaged.
A small note here, being an electrician, I'm not real excited to plug in my pup to find out if the pedestal is wired correctly. I would rather have an inline EMS that I could plug in without the pup, but I don't want to worry about theft of an inline EMS. So I did end up with a hardwired unit.
