WAZER Pro and 208V Supply

In the 60hz region, the 220-240V split phase for WAZER Pro is achieved by combining two legs/lines of 120V at antiphase. But not all power supply has split-phase set up pre-installed. Sometimes 208V is measured between two legs/lines. So, it is safe to be used for WAZER Pro? The answer is a bit more complicated, because it depends on how the 208V is generated.

If you 208V is a single phase supply generated from a Delta 3 phase supply, See picture below:

• This is not what WAZER Pro can handle

• WAZER Pro 60hz can only operate in a 220-240V Split Phase supply, which is generated using different wiring methods. See picture 2

• Split phase 220-240vac is the recommended power set up for WAZER Pro. 

• If WAZER Pro is connected to the single phase 208V supply, the GFCI inside the machine will be damaged immediately and the whole machine will be inoperable. 

If you are using a Wye connection in your supply. See picture below

• The WAZER Pro will be safe to operate under 208V. 

• However, this is not the best recommended supply. The power consumption may be higher than connected to the split phase. 

• The limiting factor is the GFCI. There are 2 hot/live go into the GFCI.  

• Please make sure each hot is less than 140V to the ground, anything above that, the GFCI will not function. 

The most ideal supply is still a Split Phase 220-240V. It is generated as the schematics shown below.

Consult a licensed electrician about the wiring set up in your facility, before attempting to connect the WAZER Pro to the power.
