Questions & Answers

Is this rated for use with EV chargers?

Asked by: chris27
The 3894 is rated for 50 amp circuits which allow up to 80% (40 amps) continuous load and 100 % load (50 amps) for up to 4 hours. Devices are tested for heating at 100% rated load (50 amps) after undergoing 100 cycles of inserting and with drawing a plug making and breaking a 150% load (75amps), and 250 cycles prior to dielectric voltage break down test. An EV charger is highly unlikely to draw full rated current when first plugged in so you will never see the degradation of the receptacle and plug blades we see during testing, so the receptacle should function at lower temperatures than allowed by UL under normal use.

What is the box fill for the 3894

Asked by: Anonymous
Per NEC 314.16(B)(4) For each yoke or strap containing one or more devices or equipment, a double volume allowance in accordance with Table 314.16(B) shall be made for each yoke or strap based on the largest conductor connected to the device(s) or equipment supported by that yoke or strap. Lets assume you are using 6AWG wire (good for 55 amps at 60C) the table requires 5 cubic inches for each 6 AWG conductor. Since a device requires a double allowance in this scenario the device would require a deduction of 10 cubic inches. The rest of the deductions would be determined by how the device is wired. The number of conductors, clamps, grounding conductors used in the installation would need to be known. Please note that the size of the deduction for the device is based on the wire size. So, if you are using a higher rated wire (75C or 90C) for the installation the overall size of the deduction for the device would decrease.
