Customer Questions & Answers

Will this Load center work with Older model homes constructed with aluminum wiring?

I am making upgrades to my home and I want to install A new Breaker Load center. I want to know if this INDOOR MAIN BREAKER LOAD CENTER , can be installed into my home that has aluminum wiring through the house that was built in 1974. or will I have too rewire the whole house with updated COPPER WIRING?
Asked by: Bobthehomeowner
Get multiple estimates from licensed, bonded, and insured electricians to rewire your entire house with copper Romex & bring it up to current Code. Single strand aluminum branch wiring is not well suited to modern large current appliances (e.g. vacuums, saws, and hairdryers) and over time oxidizes and can cause fires. Use your favorite search engine to query "aluminum wiring fires." I am currently closing on a house built in 1978 that was inspected and found to have aluminum wiring. I am splitting the cost of full replacement with the seller ($8,000). The price was an easier pill to swallow than the risk. I am located in northeast Florida if you need a geographic reference for the price differential. After closing, I will pitch in another $2,500 to have a service main upgrade back to the street using a 4-wire service cable & the 200A Square D QO panel listed here. I look forward to doing many projects with many large power tools without worrying about the lines overheating and the outlets catching fire. Basically, I recommend that you solve your main problem first before you solve any others. [pun intended!] Good luck!

what circuit breakers do i need for a homeline brand panel?

Asked by: danny
Though the HomeLine is probably a fine series that gets the job done, save up a little longer and get the superior QO series. The Specifications page and the marginal price difference should be all the convincing you need to buy the "heavier duty" lifetime warrantied product.

This panel is listed as 30 Space 40 circuits. Other load centers are described as 30 Space 30 circuits and have basically the same specs. Where is the 40 circuit designation coming from? I assume they are using half width double breakers but is the buss bar thicker or enhanced?
Asked by: Kevin
QO3040M200VP is 30-space load center designed to accept QOT tandem branch circuit breakers to provide maximum of 40 single pole circuits.

Customer Reviews

QO 200 Amp 30-Space 40-Circuit Indoor Main Breaker Load Center with Cover Value Pack is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from great panel, get parts everywhere After years of messing around with other panels, i found this QO box from Square D. A name you can trust. Simple install, plenty of spaces, and if you need breakers, you can go just about anywhere to get them. Used this for my new shop, and as a replacement in 2 homes. Doesn't get any easier. Just don't forget to get all your breakers when you get the panel or you'll be making a trip back out to get them.
