Resolution:
The HCM36918M used the MAP main breaker and is obsolete. The HCM36918MP uses the MGP main breaker and also requires the deeper box, HC3291DB9. Often cross-referenced or updated with the 'P' suffix variant HCM36918MP specifies minor packaging or optimized commercial listings for the exact same physical frame and electrical specs, currently both HCM references are obsolete and replaced by HCJ family.
