I thought this might help folks make an informed decision when they have limited power in shop. Actual currents are usually much less than what is listed on the label. All measurements made with motor idling. I made these measurements with a inexpensive clamp meter. I noted maximum current that I saw. Since this is not a true RMS meter a fudge factor of 10% should be sufficient to provide worst case current.

KF700 Machine Label. Measured shaper 3KW motor.

Measured Starting 18A. Idling 2.8A. I had previously measured current with a scope on this machine and a peak current of 4A matches the RMS reading I took.

3/20/21 Update. Measured shaper current with Felder 04-2-098 rebate head installed on 30mm spindle. This is a good size steel body cutter at 150mm dia & 51mm cutting height.
Measured Starting 38A. Idling 3.0A.


K975 Machine Label. Measured saw motor (5.5KW) alone and Saw & Scoring (1.1KW) motors together.

Measured Starting 24A. Saw idling 4A. Saw & Scorer idling 5.7A.


Format4 Dual51 Machine Label. 7.35KW motor.

Measured Starting 38A. Idling 6.2A. I had previously measured current with a scope on this machine and a peak current of 10A equates to 7A RMS. So I would suggest using 7A.

Hope this is helpful.
