2 wire vs 3 wire ballast. This will bring inconvenience if the existing ballast is not compatible with the plug and play led tubes. The other end of the ballast has 2 ports one has 2 blue wires and a red wire coming out and the other port has 2 blue wires a red and a yellow wire. I have some t5 work horse which has red and yellow. The way to work out how to wire it is to trace the pairs of cables from the lamps back to the ballast translate them to the same pair on the new ballast.
These translate directly to 10 11. Just one black and one white. Multi wire configuration the 2 circuit multi wire configuration requires that the black and red hots be attached to a two pole circuit breaker that has a tie bar so that these two circuits are not fed from. My twin tube ballast has 2 blues and 1 red.
Above are three generic examples of an 8 terminal 7 terminal and 6 terminal ballast. The ballast compatible led tubes work only with selected types of ballasts. 1 there is no green wire coming out of the left of the ballast. 7 wires in total.
Removed an old ballast from a fluorescent fixture the old one has 3 ports on one end is the port that has the black and white wires the power. Ballast quantity and location may differ from that shown based on type and availability. Ballasts have certain colors for individual wires to lampholders and other colors for common wires to holders. The red goes to one end of both bulbs and the blues each go to the other end one blue wire per bulb.
Wire colors for individual and common connections on fluorescent ballasts will vary depending on ballast type brand and the number of lamps they support. Ballast wires are very small in size so make sure your wire crimps or wire nuts are sized for small wiring. Two wire house wiring can be dangerous because it carries. I have indeed connected the two blue on the right side of the ballast with the two blue on the right side of the lamp as well as the two.
2 wire vs 3 wire the third prong on an outlet is typically called the ground the ground wire provides an alternate path for electricity that may stray from an appliance or product. A 3 wire circuit black red white and the ground cable can be used for feeding two circuits that will share the neutral and ground wire. Not recommended for dimming or energy saving lamp applications consult factory for additional information. Having a ground wire is very important and has been required as a safety feature since the early 1960s.
However modern ballasts vary substantially in type and complexity. 2 from the left side there is one red one blue and one yellow wire that are not reflected in the diagram below. The same thing goes for any wire nuts used. Make sure and leave enough wire sticking out from each ballast end.
Standard whip length is 9 11 option available. Moreover a ballast has a limited life and must be replaced after failure. Taking from 8 to 7 terminal first pair on the 8 terminal is 9 10.
