Fsp 221b D L3 Wiring Diagram/

Splices are used to connect wires together and are referenced on the L3 wiring diagram with a designator BS or SP (Figure 4-30). The three types of splices that are typically used on the wiring diagrams are solder splices (Figure 4-31), mechanical (crimp) splices (Figure 4-32) and lash splices (Figure 4-33). Figure 4-30 [B] Splice Types. To begin wiring your 3-phase circuit, you'll need to make sure that you have all the necessary materials. The list of items you'll need includes: an electrical panel, a three-phase breaker, an L1, L2, and L3 supply line, three-phase wires, appropriate wiring connectors and terminals, and grounding rods or cables.

This is the wiring diagram as above instead showing wiring for 3-phase load circuits. This way, two RCD's are used to split the load i.e. first RCD controls and protects the three phase load points connected to the upper 3-poles MCB's Bank. Similarly, the second RCD protects the three phase power circuits connected to the lower 3-P MCB's.. The other ends are called the line end (denoted as 'L1', 'L2' and 'L3'). The voltage between two lines (for example 'L1' and 'L2') is called the line to line (or phase to phase) voltage. The voltage across each winding (for example between 'L1' and 'N' is called the line to neutral (or phase voltage). Voltage Relationship
