+# Wiring Methods Selection
+
+Seek to use the cheapest method,
+as determined by Senior Construction Estimator
+and Database Administrator,
+as allowed for the situation.

+
+## By Construction Type
+
+See [[ibc-construction-types]] for more info.
+
+### Construction Types I, II
+
+Nonmetallic-sheathed cables (NM, SE, etc.)
+are not fire code permissible in these types.
+
+PVC < MC < EMT < IMC < RMC
+
+### Construction Types III, IV, V
+
+NM/SE < PVC < EMT < IMC < RMC
+
+## By Wiring Method
+
+### Electrical Metallic Tubing (EMT)
+
+#### Fittings
+
+Set-screw < compression
+

+> EMT has a third coupling type "indenter",
+> which are crimped onto the conduit using a special tool.
+> These are usually only mentioned in specifications
+> to say that they are unacceptable.

+
+### Rigid Polyvinyl Chloride Conduit (PVC)
+
+Not usually permissible exposed indoors in any construction,
+except in Florida.
+
+May require rigid stub-ups in certain cases,
+which could make EMT more cost-effective.
+Consult with the Senior Construction Estimator in this case.
+
+## By Use-Case
+
+### Multi-Circuit Homeruns
+
+> [!quote] Art Baldwin (pp.)
+> Multi-circuit MC is not cost-effective
+> when considering the difficulty of rework.
+> Use conduit, even EMT if necessary.
+
+## By Market Type
+
+### Assisted Living
+
+MC-AP may be required.
