The L H Dottie Co EC400 is a 4-inch clamp-on entrance cap designed for use in electrical service entrance installations. The clamp-on design allows the cap to be secured to conduit without threading, making field installation straightforward for licensed electricians. The entrance cap redirects the service conductors downward at the point where they exit the conduit and enter the weatherhead, helping to keep moisture out of the raceway. Sold individually, this fitting is a standard hardware accessory used in residential and light commercial electrical service work.
This entrance cap is appropriate for outdoor service entrance conduit terminations where a clamp-on attachment method is preferred or required. It is commonly installed at the top of a service entrance conduit run, bridging the transition between the overhead utility conductors and the interior wiring system. Electricians working on new construction or service upgrades will encounter this type of fitting as a routine component of the service entrance assembly.
Designed as an OEM-style replacement and standard-fit component for 4-inch conduit service entrance assemblies in residential and light commercial electrical installations.
Installation should be performed by a licensed electrician in accordance with NEC requirements for service entrance equipment. De-energize and coordinate with the local utility before working on or near service entrance conductors. Secure the clamp-on cap firmly to the conduit to ensure a weathertight fit and stable conductor routing. Inspect the fitting for proper alignment before completing the service entrance assembly.
