He needs a 60 amp OCPD and thus #6 is really a minimum. 37.8a will trip a 40.The tag says the ac unit requires a min ckt size of 37.8 amps. An amp draw of 37.8 amps would require a wire size of #8 up to 75 feet from the source (breaker). If the ac unit is over 75 feet from the source you must upsize the wire to a #6. You will also need a double ckt breaker with a 40 amp over load rating. According to the tag you could use a 60 amp supply max, but the cost t run a 60 amp ckt and larger wire would be considerable higher and unnecessary.
Won't pass inspection. Sure wouldn't do a hot start w/o tripping a 50. Gotta understand your electrical a little better when it comes to motor loads (ie: compresser).For sure its always better to run a max size ckt but sometimes its not an option with a normal residential breaker 100 amp service. Most of the time ac units don't run at there max load in this case 37.8 amps unless the condenser is plugged or there is a problem with the compressor. If I were installing this unit for a customer I would for sure run a max ckt size but if it were for myself I would feel fine running a min supply as long as it was rated above the max amp draw of the ac unit manufacture tag.
This will work electrically speaking but you only need 14-2 (ground isn't included in the -2 but it's there) I would recommend using some SJOOW cord.I need to extend my lamp cords 20' and all of the supply houses are out of lamp cord extensions. The plan is to severe the lamp cord and insert a length of wire in the middle, reconnected within a Jbox on each end. So Lamp socket>Jbox<wire>Jbox<end of lamp cord>plug into ballast.
I see that the lamp cords are only 16awg so 14/3 romex should be sufficient right?
Nope. On computer monitors, flat screens and the like they pop s ferrite rfi supressor but not on lamps.Snaps, doesn't a modern lamp cord have some shielding to prevent RF interfernce?
