GE breaker types

I cannot determine the difference between ge THQP 250 and THQL2150. I am needing a 50 amp 240 v circuit for a welder and have a ge box. Are these interchangeable?

The first appears to be a 2pole 50A breaker. The second appears to be a 2pole 150A breaker, used as a main. I would think you could find what you need at a big box store.

THQP breakers are narrow - half the width of THQL breakers. They might save space but may or may not fit in specific panels and may or may not buy you anything.

This from page 6 of the GE PDF.

Because of the way 2-pole THQP breakers straddle legs in a breaker panel they may or may not save space. You will need two free adjacent slots regardless. I'd say use THQL - the full-size breakers - unless 1) your panel accepts THQP [not all do] and 2) you expect to be adding other circuits and 3) you're short on space.

Look on the inside of the panel door. It should tell you what the model number of the box is, and what types of breakers it will accomodate.
