Wiring 2 Ballasts In Series

Wiring this can be done a number of ways.

Wiring 2 ballasts in series. Dimming control wires are not affected by em pack. This happens all the time and is no big emergency. If you had a double lamp fixture with it s double lamp ballast and two lamps hooked up and running and then one of the bulbs burned out early the other one would still work fine. A black a white one red one blue and one yellow.

This is because the wire colors on the ballast and the lampholders do not match up on two of the connections. A 4 lamp fixture with two series ballasts can be replaced with a 4 lamp parallel ballast. With a two lamp series ballast if one lamp fails the other lamp connected to that ballast will not light. However 12v dc is enough to run three in series 3 x 2 98 8 94v dc.

Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. Series wiring uses a non shunted lampholder with each side of the lampholder isolated from the other side. You will need to cut the neutral wire loose from the bulb. As seen below connecting the 4 lamp parallel ballast to the four lamps can be a bit confusing.

And from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings. The old ballast had two blue and two red wires on the right and on the left side. This section of the circuit then is an example of wiring in series. Ballast lamp lamp ac emergency lamp two lamp series magnetic ballast emergency ballast 2lsmb advance h 2q18 tp h 2q26 tp v 2b9 tp all compatible ballasts may not be listed.

However should the gfci go bad then all the connected downstream outlets will also cease to function. Using another length of nm cable connect the black wire that you connected to the first fixture the black wire from the second fixture and the black wire from the second length of nm cable together with an orange wire nut. Wire to the next fixture in the series from the fixture you wired first. The load terminals can be used to extend wiring to additional regular receptacles beyond the gfci which allows them to also enjoy gfci protection.

The black connects to a red power wire in the ceiling the white to the whtie neutral and the single red blue and yellow wires all connected to matching wires on the fixture to the left. Rule number 2 from the series circuit bullet points proves that 12v dc isn t enough voltage to run all 9 leds in series 9 x 2 98 26 82v dc. That way two blue wires go to one end of the bulb and two red wires go to the other end of the bulb and the 100v hot black and neutral white go only to the electronic ballast. Connecting a blue wire to a neutral white wire will burn out your electronic ballast.
