The Siemens SIEFPP1C18ML250AT is a complete P1-series panelboard rated 250A, 120/208V with an 18-circuit capacity and a Main Lug Only (MLO) configuration — meaning it requires a separately installed upstream main disconnect or breaker. It is compatible with Siemens P1-series plug-on breakers (single-pole, double-pole, and tandem/twin where space permits), making it well suited for both new commercial and residential service installations and panel upgrades or sub-panel applications.
If you need to confirm breaker compatibility, branch circuit configurations, or upstream feeder requirements for your specific installation, send us your project details and we'll confirm the right fit.
MLO stands for Main Lug Only — this panel does not include a built-in main breaker. It must be fed from an upstream main breaker or disconnect switch. This makes it ideal for use as a sub-panel or in installations where the main disconnect is located elsewhere, such as at a meter base or distribution board.
This panel provides 18 circuit spaces. Depending on your jurisdiction and the breaker types used, you may be able to increase circuit count using approved tandem (twin) breakers in designated spaces. Check the panel's directory and local electrical code (CEC) requirements, or contact us and we can help clarify your options.
