Can a splice box be used to feed a sub panel?

Yes, a splice box can be used to feed a subpanel, provided it is appropriately rated for the electrical load and complies with local electrical codes. The splice box should serve as a junction point for the conductors supplying the subpanel. It’s essential to ensure that all connections are secure and that the box is accessible for maintenance or inspection. Always consult a licensed electrician if unsure about the installation.
