3.1 GENERAL WIRING CONSIDERATIONS
American Rotary recommends that a qualified electrician should do all wiring and make all the connections .
It is important to have adequate single-phase electrical service . The actual single-phase current that will flow
through the converter is approximately 1 .73 times the three-phase current . The National Electric Code requires
2 .5 times the three-phase load current to allow for starting current and a margin of safety . This is a good
conservative calculation to determine your single-phase branch circuit wire size and breaker size . The power
needed to run the phase converter is very small and is negligible in figuring out the power required . The power
required is calculated based on the load(s) only . Please see the list below for additional considerations when
wiring the converter and your equipment .
•
American Rotary recommends the use of copper wire . If you choose to use aluminum wire make sure it is
upsized properly, as it does not carry the same rating as copper .
•
Follow all local, state and national electric codes (NEC) which may supersede American Rotary
recommendations .
•
Increase wire size one size for every 50 feet of run and round up .
•
American Rotary highly recommends surge protection to be installed on the single-phase side to prevent
damage downstream in case of a power surge caused by lightning strikes, brown outs, etc . American
Rotary has affordable options for this in stock .
•
T3 is the manufactured line; DO NOT use T3 for any single-phase loads such as start circuits, controls, etc .
Run all control voltage and equipment controls from lines L1/T1 and L2/T2 . Terminals A and B are for the
idler only .
•
Always make sure that the rotary phase converter starts before external load(s) are applied . This includes
transformers that are connected downstream of the converter . American Rotary offers a number of
automatic and manual disconnect solutions to ensure all loads are disconnected before attempting to
start the converter . Failure to do so can result in serious damage to the converter and your equipment, this
will also void your warranty .
•
DO NOT assume that a breaker box neutral is a ground . Be sure to ground all equipment including breaker
boxes, phase converter control panel and idler, disconnect switches, transformers, loads etc .
•
Wire can never be sized too large, but too small of wire can impede performance and even keep the
converter from starting properly .
