To test effect of the motors on the leakage current, they were cycled once per hour overnight at approximately 50 minutes past the hour. - attachment 1
Leakgage current was seen to decrease slowly overnight before flattening out.

At 11:25 This morning the FEEs were powered on. From this point on the leakage current was observed to start to increase. - Attachment 2
Note the time recorded by the pi logging the leakage current is approximately 2 minutes ahead of the FEE.

15:40 I notice again that powering on the FEEs causes a momentary increase in the leakage current. - Attachment 3
