Advanced conduit bending
Offsets, saddles, kicks, rolling offsets, and concentric bends, with the trigonometry written out.
Study notes
Interests
Jeffrey’s main interests are advanced conduit bending, industrial work, and data centers. Everything here is written as a professional interest. It is not a claim that he has performed the work.
Employers ask about this first
Electrical safety
Arc flash, shock boundaries, lockout/tagout, lifts, and the competent-person designation on his training card.
