Yup, some ambiguities here...

If you raise the landing gear and the fuse blows, then watch those limits. A 30 amp or a 40 amp won't help this. If you aren't exceeding the raise limits then there might be some extra binding or problem that stresses the motor to cause the fuse to blow. I'm gonna guess this is not hydraulic. Please someone confirm.

For the slides, if you extend or retract and things stop, this operation uses an autoresetting breaker. Wait a few seconds, then resume. If this keeps happening, there are several causes for this. 1.) make sure the batteries are very charged or connect to the TV (with the motor running) or to shore power to add some extra 12v power (from the TV batter(ies) or RV converter on shore power) to workaround this issue. 2.) Check that the rear stabilizers are down (to prevent extra movement and stress as the slides move). 3.) Check the fluid level of the reservoir when the slides are fully retracted and ensure it's filled properly (probably with ATF Type A or check your manual regarding slides). Finally, 4.) the autoresetting breakers are underrated and then you need to replace the existing one with a higher rated breaker (e.g. 80 amp) or dual breakers in parallel (two 40 amp). It's recommended if you go the dual breaker route, get two new ones so they are probably the same age.

Operating the slides should NEVER blow the fuse for the landing gear. If it does, get the electrical checked out because there's probably a bad connection somewhere. Hopefully, you are not trying to operate both of these at the same time!
