Not only I found the breaker I needed for $75 cheaper than whats available locally, but I ordered late on a Thursday and got the breaker less than 24h later on Friday! Couldn't ask for more from any online shop.

I had a couple of circuits in my 4-5 year old home that were popping under minor loads (couldn't run more than 1 normal PC in a room). I dug about in the circuit panel and discovered that both of the circuits were controlled by these fault-controlled breakers that are now often used where an outlet is near a water source. I replaced the two switches (turn off power to the panel, 4 screws to open it. pull the old breaker, 3-4 screws to wire-up the new breaker, clip in the new breaker, close up panel, turn on power... check YouTube for a how-to) and poof! Everything works as it should again.

Used this to install . Worked fine.
