I see the last thread is older, so I started a new one for this specific issue. Apologies if this was inappropriate. My friend has an old Advance Transformer Company ballast RQM-2S40 (pic attached) that drives two 40-watt flourescent 4 foot bulbs. Residential (in basement). The ballast is now dead. I need to change it out (currently using T12 F40T12 40 watt 4 foot bulbs). I would like to change out the ballast with a Philips Advance Ballast RELB-2S40-N. This appears to be a good replacement but I am no expert so if possible please advise if this ballast is an appropriate replacement or I should consider a different ballast. [U]Not that I am buying it from Home Depot, but here is a link to the product (if more info is needed):[/U] [URL]https://www.homedepot.com/p/Philips-Advance-AmbiStar-40-Watt-2-Lamp-T12-Rapid-Start-High-Frequency-Electronic-Replacement-Ballast-520395/202960408[/URL] Thank you in advance for your assistance!

ok guys I’m at my wits end here. In the attic I have a junction box with 4 wires going into it. The reds with the reds, black with black, etc. Now, in the living room I have 4 wires coming out of a junction box, black red white and ground, the red and black are hot. 120v on each. I try to connect a 3 way switch and it flips the breaker. Black wire to the black nut and red wire to the one above that one and the white wire on the opposite side of the black nut. On the opposite wall there is already a 3 way switch and that’s how it’s wired. Now if I completely remove the switch in question then the light works correctly because of the other 3 way switch but if I flick that other switch off then it flips the breaker. Can anyone tell me what’s going on? Thanks.
