What code section allows 15 amp switches on 20amp circuits?
What code section allows 15 amp switches on 20amp circuits?
What code section prevents 15 amp switches on 20amp circuits?
404.14 Rating and Use of Snap Switches. Snap switches
shall be used within their ratings and as indicated in
404.14(A) through (F).
(A) Alternating-Current General-Use Snap Switch. A
form of general-use snap switch suitable only for use on ac
circuits for controlling the following:
(1) Resistive and inductive loads not exceeding the ampere
rating of the switch at the voltage applied
(2) Tungsten-filament lamp loads not exceeding the ampere
rating of the switch at 120 volts
(3) Motor loads not exceeding 80 percent of the ampere
rating of the switch at its rated voltage
I think this section allows it.

Hmmm....so 100 amp meter on a 200 amp service ok then? Maybe its just comes down to a 110.3(B) argument.....?
A meter is not a switch.

What would you cite for a violation?
I knew you would say that :lol:
So Dennis's code blurb would be the most applicable provided that load does not exceed 15 amps?
I think so.
But why does the NEC then forbid a #14 to a light when the circuit into the switch is #12 fused at 20amps?
Because the NEC explicitly requires that the OCPD protects the wires. It does not, however, have a general requirement that it protects any devices attached to/in the circuit.
The 100A fused disconnect on a 200A service is not the best example case since it incorporates its own OCPD and that OCPD protects both the disconnect itself and any downstream wiring. (Where a tap rule applies, it may also protect the upstream wiring.)
But heres my point, if the reason for all #12 on a 20amp circuit is in case down the road the wire is extended which might subject it to overload, then why not include the switch?
