Figure 3. Relationship moments in balance The proposed crane in this paper reduces the ballast and eliminates the anchor, since it will be auto balancing''. The concept of self-balancing involves eliminating anchoring system, which is replaced by a movable counterweight as shown in Fig. 4. Figure 4.
L5-20 and L5-30 Cords â 120V. Many of the higher end portable generators have a L5-30R outlet. This is handy as it allows you to connect a L5-30P to the generator and use a multiple type 5 outlet at the other end allowing you to use 2 or 3 tools or appliances that use less than the total rated amps or 3600 watts.
If you use an undersized cord, you can potentially damage the generator and appliances. For example, the most common size for generator use is 14, 12 and 10 gauge. The smaller the gauge number, the thicker the cord and the more electricity it can carry. Extension cords have several other drawbacks. First, most extension cords can't be plugged into a furnace, well pump, or ceiling-light fixture.
