This demonstration guide answers one field question about a loose receptacle that drops voltage under load. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with thermal imaging or temperature at the outlet face. That reading separates a loose receptacle that drops voltage under load from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the receptacle as the primary path. If it is in spec, do not replace the receptacle just to complete a parts list.
Repair the failed system
The usual correction is the receptacle, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a loose receptacle that drops voltage under load.
Stop before you make it worse
Do not cheater adapters that overload a 15-amp outlet. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the receptacle is corrected, convert the visit to a broader diagnosis rather than stacking parts.
