What does Square D QO mean?
Qwik-Open
The “QO” designation stands for “Qwik-Open”; Square D claims these are the fastest-opening breakers in the industry, responding within 1/60th of a second, or just one full power cycle on a 60 Hz AC line. A second miniature circuit breaker line is sold under the brand name Homeline, marked “HOM”.
What is the difference between Square D Homeline and QO?
Homeline is the “price competitive” model from SquareD, QO is the higher quality panel. The difference is probably mostly due to historical reasons given all the consolidations in the electrical manufacturing industry.
What is QO Breaker Square D?
The Square D “QO” line of miniature circuit breakers is their best-known product line. These “Qwik-Open” or QO breakers are the fastest opening breakers in use in the industry. They reportedly open after just one full power cycle of a 60 Hz AC line (about 1/60th of a second).
How many amps can you put in a 200 amp box?
160 amps
In general, a 200-amp panel should handle no more than 160 amps at once. It’s important to note that people can have 300 or even 400 amps worth of breakers in a 200A panel, as they don’t use all circuits at the same time. Calculating how many circuit breakers you need is also dependent on your home electrical loads.
