Steel City 52151 3/4 – Frequently Asked Questions
1) I need a box for a range or dryer receptacle - will the Steel City 52151 3/4 work?
The 52151 3/4 is a 4 x 4 x 1-1/2 inch steel square box with 21 cubic inches of capacity, sized for general single-outlet device and splice work. For a range or dryer outlet, the Pass & Seymour P242RRD thermoplastic range and dryer box is the purpose-built option.
2) What is a non-metallic alternative to the Steel City 52151 3/4 for residential rough-in?
The Steel City 52151 3/4 is a 4 x 4 x 1-1/2 inch steel square box with 13 knockouts, intended for wall or ceiling mounting. If you want a non-metallic box for residential work, the Cantex EZ Box series is a PVC multi-gang residential outlet box. Note the EZ Box is multi-gang and the 52151 3/4 is a single-outlet square box, so device plates and ring selection differ.
3) Is the Thomas & Betts 2IH3-1 Red-Dot a direct substitute for the Steel City 52151 3/4?
They are different box styles. The Steel City 52151 3/4 is a 4 x 4 x 1-1/2 inch square steel box with 13 knockouts for wall or ceiling mounting in a dry location. The Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs, so conduit lands on threaded hubs rather than knockouts and it covers two gangs of devices.
