Electrical Wiring in the Home/Puma PK6060v setup

Advertisement


Question
picked up a Puma PK6060v and I m trying to hook it up and wondering if anyone can help. the motor says 115/208-230v and 30/16.2-14.7 Amps .
I am planning on setting a 220v receptacle, here are my questions
I tested my lines and I have each hot measures 120 - 124v , when using two of the hots that would add up to 240-248v
Q1 : how would I make sure to stay within 230v max as recommended.
Q2 : what type of wire should I get knowing that the distance from the main box to the guarage is almost 70feet.
Q3: the motor says max 16.2 amps , will a 20amps breaker be sufficient or should I go lower (is there lower than 20amps)

appreciate any help

Always check with the local “Authority Having Jurisdiction” for an official interpretation before making installation decisions.

In Philadelphia, it is unlawful for anyone except an individual licensed by the City of Philadelphia to install electrical equipment and wiring.
Homeowners are not allowed to install wiring.

The limited exceptions include replacing devices and fixtures at existing outlets.
Contact the Department of Licenses and Inspections for more information.

You are more likely to be killed by 120 volts than any other voltage [120 volts creates the PERFECT fatal current through the human body's electrical resistance!]
TURN THE POWER OFF WHEN WORKING!

Q1 : how would I make sure to stay within 230v max as recommended.
You have no control over the voltage so as to stay within the stated "max" What the 208/230 means is that the motor will run on either 208 or 230 nominal/240/whatever is being delivered

Q2 : what type of wire should I get knowing that the distance from the main box to the guage is almost 70feet.
This question is more appropriate after the discussion of current

Q3: the motor says max 16.2 amps , will a 20amps breaker be sufficient or should I go lower (is there lower than 20amps)
A 20 amp breaker would not be adequate at 16.2 amps if the compressor is running continuously for more than four hours, so if you will have the motor running non-stop you would have to allow for 20.25 amps [125% of load], which means 30 amps, like it or not, and 10 gauge wire.
HOWEVER, that 16.2 amp value is for operation at 208 volts, not 240. At 240 [or your 248 or nominal 230] volts the current would be 14.7 amps, which would require only 12 gauge wire. Voltage drop using the formula Vd=KIL/CSA would give 11*14.7*(2*70)/6529 or a voltage drop of 3-1/2 volts, which is excellent.
