Temperature code

Ambient limits belong to a housing and voltage row.

T-code and maximum ambient vary across the B-Series. Match the selected row to the site classification, then confirm the exact marking on the ordered luminaire.

Scroll horizontally to compare every documented thermal row.

Common questions

Frequently asked questions

These answers clarify the selection process without replacing project-specific documentation.

What hazardous-location listings are available for EPC-B?

EPC-B is listed for UL 844 Class I Division 2 Groups A-D, Class II Division 1 Groups E-F-G, Class II Division 2 Groups F-G and Class III, plus UL 1598 Wet, UL 1598A Marine Outside Type, ABS, NEMA 4X, IP66 and 3G vibration.

Which EPC-B wattages are selectable?

B2 offers 40/60/80 W, B5 offers 60/80/100 W, BX offers 120/150/200 W and B4 offers 200/250/300 W. B4 is also available in fixed 350, 400, 500 and 550 W configurations.

How do I select the right EPC-B housing?

Start with the required wattage and lumen package, then match the voltage range, ambient rating, temperature code and mounting method. Maes Lighting can prepare the complete catalog number for the project.

Can Maes Lighting provide photometric files?

Yes. Request the photometric package for the selected housing, wattage and optical configuration during specification review.

Are A1, B1, C1, D1 and I1 separate EPC-B luminaires?

No. They identify ceiling, U-bracket, wall, 25-degree pole and pendant mounting methods for the EPC-B family.
