Dear Mr. blaze777 (Electrical)
"...I have a box full of these breakers, not sure how I aquirred them, and they have no identifying marks or labels. They resemble a GE Twin. THe only label is a UL Listing lablel. Can anyone help me identify brand and what panel they will fit?..."
Che. 1. Sir, you are not sure how you acquired them, no identifying marking or labels, but only label is a UL listing.
This is probably? a [rejected item that failed the manufacturer's quality control]. This is why there is [no name of manufacturer , model and rating marking]. These rejected items are to be [destroyed] instead of allowing them to flow back into the market.
2. DO NOT attempt to use it all, irrespective of who was the irresponsible manufacturer/contractor who was responsible for the disposal! It is a potential time bomb. [Destroy] it and dispose of it. Prevent it from coming back into the market again. Thank you.
