Customer Questions & Answers

Can I use a tandem breaker with this panel?

I currently have a maxed out panel and am wondering if a tandem or suboanel would be the way to go with my current 100amo service.

Asked by: jay
no, it's a main lug panel. you can back feed a 100A breaker to act as main.

Can i use this for sub panel ?

Can i use this for sub panel ?
Asked by: Young
Young, No. Rule of thumb is Main Lug (Sub Panel) can be converted to Main Breaker, but you can't convert Main Breaker back to Main Lug. I would suggest our P2020L1125CU. That is the same product but as a main lug.

converting from main to main lug

What is needed to convert to a main lug. I will be using it as a sub panel.
Asked by: Joe
Hi Joe, This panel is able to be converted to main lug, simply remove the main breaker that is installed after you receive the product.

PL Series 100 Amp 20-Space 20-Circuit Main Breaker Indoor Load Center is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Worked great nice product ... Worked great nice product
Date published: 2017-04-22
Rated 5 out of 5 by from IT DOES INCLUDE THE MAIN BREAKER! The documentation is vague. This panel DOES include the 100 amp main breaker fully installed. It DOES include the surface mount cover. And you do not need the breaker clamp for the main breaker either. Folks, please do not buy the other panels with aluminum bus bars. Aluminum is only a few dollars cheaper than these genuine copper main bus bars. Especially if you have motor loads like A/C compressors and well water pumps.

Rated 5 out of 5 by from Looks good, easy & flexible to install. ±100$/30+ years = Worth it. Or ±0.27$ a month. Math.
