Pretty easy to install. Removed breaker with 2, 15 amps to accommodate the 30 amp. Charges my Ioniq 5 at 6.7 kilowatts level 2. No faults and works perfectly. Before I was charging really slow at level 1. I charge mostly for free but occasionally I will use my home charger.

This is a convenient way to add two circuits to a Progressive Dynamics RV circuit breaker panel and maintain Original Inverter prep and have more space to add GFCI breakers. PD uses Siemens breakers exclusively. Recommend to use breakers rated to panelboard to maintain rating & underwriter listings.

This was a direct fit replacement for a breaker that was sticking. Couldn't find it ANYWHERE at the box stores. The design is kinda lame, but so is the quality of my modular house. I am thankful, though that I can get a replacement. Would have had a lot of re-wiring to do. Best part of the whole deal was the $25 price. I was expecting 10 timea that amount!!! Very pleased!

Our old one melted (scary) and not only was this configuration hard to find locally it was WAY to expensive. Ordered from Amazon and received it next day. Slid it in the spot and we are back up and running. Still going strong after a few months.

Je ne sais pas s'il s'agit d'une copie mais ça ressemble à cela. La fabrication est presque similaire mais il y a une différence et ne fait pas dans tout les panneaux. Il ne s'insère pas à la perfection. Nous devons porter une légère modification qui est contraire à l'éthique.

These breakers to not fit my seimans panel they look identical except the grove where the connection is made is not deep enough. My panel is in a 10 year old house so I don’t see it being an age of panel problem.These seem to be a defective product as I don’t see anything online that there is two different styles of breakers and I was able to just buy ones at the hardware store and they fit right in. I will be returning them.The breaker sent to me on the left breaker from my panel on the right.
