Looked up codes but still confused whether this allowed or not .Saw the 40% rule . But have always put sub panels on its on breaker .This is on a residential house built in the 60's ?
 
What is your question?

Do you have a separate panel fed without a breaker from a splice on the service conductors? Is this separate panel located next to the main panel? Is this separate panel supplied with separate ground and neutral?

Can you post a photo?

Trying to post picture but can't find a way to pull from gallery. It is a 200 amp panel with wires going to 150 amp sub panel . Wires were skinned and some type of split bolt added and then just regular black electrical taped .
 
This is the main panel with wires spliced going to the sub panel. I always run separate breaker for the sub . Plus that kinda is beyond the 75% rule .

Then nothing wrong with it in general, other than the devil of some details. What you have basically becomes a 230.40 exception #2 install, done every day in commercial work. Details of concern would be the length of the service conductors, whether that second panel has a service disconnecting means, and details of the grounding electrode conductor connection.
