16 amp converter?

[LHodges]

Hi

We have a APC SRT5KXLI device, which has a 32 Amp cable plug but we've moved to a location where there's only 16 Amp.  Is it possible and as simple as buying a 32-Amp to 16-Amp plug converter, or will the unit not like that?

Thanks in advance for your help,

Lee

Short Version:

Per electrical code, you can not use an adapter to circumvent the existing plug on the system to obtain power.

The system has a specific (L5-30P) plug rated to sustain 30 amps. A 5-15P / 5-20P is only rated to carry 15-20 amps at 80% capacity.

Long Version: Given you have not provided any context or relevant information about the current load on the system. I’ll simply provide some insight and information to guide you.

If the system is drawing more than 20 amps than you need to hire a licensed electrician to install a 30 amp circuit and install the correct L5-30R receptacle.

Anything less is against code, fire hazard, insurance, and voids any APC hardware warranty.

If this is some kind of DIY Home Lab the above still applies. 

Having said this, many people do use an adapter as you suggest. The only caveat is the system never (ever) exceeds the 80% rating of the 15-20 amp circuit! ☝️

NOTE: Don’t simply read the SRT UPS data to obtain the power / amperage consumption. Because it’s not even remotely accurate vs a multimeter / clamp meter.
