How do you ground a fluorescent light ballast?
Providing the power supply is switched off at the mains there is really no problem except for the following :- # New installations need to conform to part p of the building regulations as does any installation in the kitchen, bathroom or other wet rooms and may need the earth / cross bonding upgrading. # If the wiring in the old light (not the house wiring) is in the old red and black colouring this may suggest that the house wiring itself may have been around for a long time and may need checking.(The house wiring being red and black would not in itself be an indicator and may still be fairly new). # The original fitting may not have been installed correctly. For example if it is wired into the ring main instead of the lighting circuit then in needs to be connected via an appropriately fused spur. # The term standard hard wired light fixture doesn't give indication of the units loading and may be taking the existing circuit past it's safe capacity. # Any cutting or removal of fire barriers eg plasterboard needs to be protected by intumescent strips or foam. # I am not an electrician and have no vested interest but would suggest that the need to ask the question indicates that you need qualified help in case you've not considered the above or there is some other possibility that I haven't thought of bearing in mind I've never seen the site. # Mains voltage can be and often is lethal.
How do you wire a 3 prong 240 volt spur to a 4 prong 240 volt receptacle?
Your L14-30 receptacle has four positions on it. It is rated as a 125/250 volt device. It is classed as three pole four wire grounding. Connect the ground wire to the "G" screw, white wire to the "W" screw. One of your hot wires (might be red) to the "X" screw and the other hot wire (might be black) to the "Y" screw. This connection gives you the potential of 240 volts between "X" and "Y" and 120 volt potential between "W" and "X" and 120 volt potential between "W" and "Y".
