Acme Conduit Entry (ACE)

Faster, cleaner wiring

The ACE makes quick and simple transitions from USE-2 or PV array wire to conduit protected THWN-2 wire. The box features a compact two-piece UV resistant, NEMA3R rated, enclosure that allows ample wiring space and is compatible with any conduit type. The unique wire entry seals the enclosure even if entry slots are unused. Convenient side and bottom conduit drill out allow for easy conduit routing. The cover comes with captive screws for hassle-free assembly.

• Simple array to conduit transition
• Compatible with any conduit type
• Protective enclosure for connecting USE-2 or PV wire to THWN-2 wires
• Two-piece shell for unobstructed wiring
• NEMA 3R rated for outdoor use

Acme Cable Clips (ACC)

• Made with corrosion resistant 300 series stainless steel
• Dual wire compartments
• Special tab for easy installation and removal with flat-head screwdrive
• Designed to prevent damage to cable insulation
• Sized for USE-2 cable (5-5.4mm) or PV cable (6.8-7.2mm)

ACC and ACC-PV

ACME Cable Clips simplify wire management and create a cleaner aesthetic to solar PV arrays. The clips are made of corrosion resistant stainless steel and are designed to prevent damage to cable insulation. The easy to install and remove design only requires a flat head screwdriver and can be reused,unlike zip ties. The universal design fits most modules and can hold one or two wires.

ACC-R2 and ACC-R4

ACME Cable Clips simplify wire management and create a cleaner aesthetic to solar PV arrays. Made from corroson resistant stainless steel, the clips are designed to prevent damage to cable insulation and last for the life of an array with no maintenance. The ACC-R2 and ACC-R4 cable clips can be securely attached, by hand, to a variety of rails. The ACC- R2 is primarily designed to hold AC leads from a microinverter. It can also be used for other applications needing two smaller wires measuring 9.3-11.0mm or one wire measuring 9.3-14.0mm. The ACC-R4 is designed to hold one to four PV wires, 6.8-7.2mm in diameter.

WEEB (Washer Electrical Equipment Bond)

The WEEB line of products is designed to bond solar PV modules to mounting structures and create an electrical path to ground. WEEBs eliminate the need for older, more costly grounding methods and greatly reduce the amount of labor and materials used in installations. The innovative WEEB design removes the need to run ground wire to each individual module and eliminates the need for surface preparation on anodized aluminum components. To install, WEEBs are placed between PV modules and mounting rails at clamping points or at bolted connections. When anti-seize is applied and the hardware is tightened down to the appropriate torque spec, the WEEBs’ specialized teeth embed into anodized aluminum, galvanized steel, or any electrically conductive metal to establish a gas tight electrical connection. When used in conjunction with a WEEB Lug, the entire solar installation becomes safely and reliably grounded.

• Material: 304 stainless steel
• Listed to ANSI-UL 467 by Intertek ETL for use in Canada and the USA
• Maximum electrical equipment ground conductor size when used with 2 WEEBs contacting each module in an assembly: 6 AWG
• Outdoor rated

WEEBLug (Grounding Lug)

The WEEB Lug consists of a WEEB (Washer, Electrical Equipment Bond), lay-in lug, and hardware. It is used with a solid or stranded 6AWG to 14AWG copper wire, or two 10AWG to 12AWG copper wires, to provide a continuous ground on roof or ground mounted solar systems. Unlike traditional lay-in lugs, the WEEB Lug does not require surface preparation on rail or module to install. The WEEB Lug is installed using a 1/4-20 stainless steel screw which tightens the WEEB, allowing the specialized teeth to embed into anodized aluminum, galvanized steel, or any electrically conductive metal to establish a gas tight electrical connection. The tin-plated Lug assures minimum contact resistance and protection against corrosion. The copper wire is clamped by a 1/4-28 stainless steel screw, which is horizontal to the tang for easy access when mounted under a PV module. The low profile of the WEEB Lug allows it to be installed in a variety of positions and comes with hardware to mount it to a rail or through a 1/4 inch clearance hole.

• Low profile design
• Multiple equipment ground conductor allowance: one 14 AWG to 6 AWG or two 10 AWG, two 12 AWG
• Listed to ANSI/UL 467 by Intertek ETL
• Material:  Washer - 304 stainless steel; Lug - tin plated copper
• UL467 Listed
• Maximum Wire Size:  6 AWG
• Outdoor Rated

WEEB Bonding Jumper

The WEEB Bonding Jumper is used to create an electrical connection between two pieces of anodized aluminum, galvanized steel, or any electrically conductive metal which has been mechanically spliced. Long spans of mounting rails are sometimes constructed from two shorter rail sections. Manufacturers may recommend that a floating splice be used to allow for thermal expansion. A floating splice is rigidly attached to only one rail, and allows the rails to expand and contract in line with each other. In such cases, via NEC code, it is also necessary to make an electrical splice, which can be done with a WEEB Bonding Jumper. The Bonding Jumper is constructed of tin plated, braided copper wire with a WEEB attached at each end of the Jumper. The WEEBs provide a reliable, gas tight electrical connection, and the braided copper wire allows for thermal expansion.
