Update:
**I removed the burned out thermal fuse from my "Kill-A-Watt" and quick repaired it to see if I could get a better idea of the start energy the 13.5k ac unit requires.(dangerous repair...bypassed the fuse..):S
-Many repeated attempts give me an average of 27 amps(3240 watts) when the ac is first turned on, with an immediate rapid decrease to the approximate average I already calculated while running on high cool(13.45 amps/1580 watts) . The watts reading on the meter is too slow to give me a reading for start-up, so I used the amps selection on the meter. This is accurate as I can calculate/test with what I have and to me, it seems proper.
(the 50 something amps proffessor95 mentioned as "typical" had me worried)
I soldered a fuse holder inside the Kill_a_Watt and used a 250 milliamp fuse. Closest I could find.
Next... you are trying to measure what is known as in-rush current. You need a clamp meter with that capability. I measured my 13,500 Dometic yesterday. Blower and compressor pulled a peak of 70 amps. This measurement is taken in the first 150ms of operation.
I shut down the AC unit, let it rest for 15 minutes, pulled the relay wire to the fan and the compressor gave me an in-rush current of 62 amps.
I hope this helps.
How is the Kill_A_Watt doing with AC unit running through it without a fuse?
