Many people in pursuit of profit forget about safety rules when connecting electrical appliances. I don't understand why you need to measure power 24/7. your equipment consumes about the same power and you can't change that. A melted socket can cause a fire. Why do you measure power if you are not using this data?

90*c is good, right?
THis is why you run 220v. Double the voltage, half the amperage, half the heat from resistance and more efficient.

My power meter is rated up to 3600w so I should be good drawing about 1.2kW through it at any given time. But warning like this are good to see!

Well, man, you are really lucky one, imagine what could happen if that thing not just melt itself and your socket, but start a fire?! that would be a total nightmare.  I hope everything would be ok with your rig as well.
and lesson learned,  no power meter 24/7  )

same with you and I hope his Rig is fine

yeah, it's @OP content that is very simple but has many notices and resuscitates members including me about the risks which we initially considered trivial.

I passively left my power meter plugged in 24/7 while mining because i thought it would be more fun to be able to check it 24/7. Turns out it was a bad idea as this morning i woke up to a blown/melted socket and powermeter. Hopefully my rig isn't damaged.

Another reason to not keep it on 24/7 is for savings. The power meter probably consumes a negligible amount but even at 1 watt per day, that is still money saved looking at the big picture (365 days a year).

thanks for waking me up in fact, the power meter could be melt and require a power consumption so far I never unplug the power meter and not aware even that device need a power.  Grin

Do you have any idea why your power meter was melted. Basically it could stand for a massive load current.

Good point. I was running a 13-GPU rig mining at a constant 1600 watts.
I'm thinking it melted because of wear and tear because it's been mining since December without any problems at all.

Where you went wrong is running 1600w through a 15a rated device.  1600w equates to roughly 13.33a that you were running through a power meter that IS NOT RATED FOR 15a continuous duty (AKA 100% duty cycle).

I would be more concerned with your circuit breaker wiring connection being burnt, the outlet itself being ruined (I would replace it anyway since you cant inspect the internals) and the wiring in the wall that is also NOT RATED for 15a continuous duty.

A 15a circuit and all of its components (Outlet AKA Duplex, Circuit breaker and wiring) are only rated at 80% of 15a which is 12a for CONTINUOUS DUTY! Its called derating and it is a 20% derating factor.

A 20a circuit is good for 16a of continuous duty.  

Upgrade your wiring to a 20a circuit (if it isnt already) before you all burn your home down!
