1, a voltage VB at a point 210 during a speaker drive mode, i.e., when an alert tone is generated, is varied in accordance with consumption of a current such as a speaker driving current and a voltage drop VDROP across the internal resistor 204 of the battery 203. A current ...
One other point - the 5% voltage drop in the NEC includes everything - feeders and branch circuits. There are ANSI requirements for the acceptable voltage range delivered at the service point. rbulsara (Electrical) 6 Oct 09 13:51 Also what is single phase, 2 wire? I hope it is not...
On a 4 wire, delta-connected system where the midpoint of one phase winding is grounded, the conductor having the higher phase voltage-to-ground shall be durably and permanently marked by an outer finish that is___in color. d) orange Where required by the Code, markings or labels on all...
