Conversions Tech Enclosures and Disconnects
Conversions Tech® Electrical Fittings & Weather-Rated Boxes
Shop UL-listed, NEC-compliant hardware engineered for fast, code-ready installs: rigid conduit bodies (LB, LL, LR), rain-tight EMT compression fittings, high-SCCR AC disconnects, and extra-duty weatherproof boxes. Corrosion-proof finishes, pre-gasketed covers, and laser-etched torque specs cut labor and boost system reliability—ideal for residential, commercial, and industrial jobsites.
Conversions Tech™ Installer FAQ
Rigid Conduit Bodies – LB · LL · LR · T · C · X
What does a Conversions Tech rigid conduit body do?
It creates an accessible point to change direction, pull, splice, or transition conductors without a full junction box, while keeping the equipment-grounding path intact.
How do LB, LL, and LR conduit bodies differ?
All turn 90°, but the cover exits back on an LB, left on an LL, and right on an LR—vital when planning feeder pulls.
Which NEC article governs conduit-body fill and sizing?
NEC 314.28(A)(2) applies. If the body lacks marked fill info, its length must equal six times the largest raceway trade size entering it.
Are Conversions Tech bodies rated for wet locations?
Yes. Die-cast aluminum models with EPDM gaskets meet NEMA 3R/4 when cover screws are torqued to 35 in-lb.
Can I bury an LB underground?
No. NEC 300.5(D)(3) requires conduit-body covers to remain accessible. Use a listed direct-burial splice box instead.
EMT Compression & Set-Screw Fittings
Compression vs set-screw EMT fittings – what’s the difference?
Compression styles are UL-listed rain-tight and concrete-tight; set-screw styles are for dry locations unless specifically listed rain-tight.
Can a set-screw connector be used outdoors if pointed down?
Only if its UL listing permits that orientation. Most installers choose rain-tight compression fittings for reliability.
What torque applies to EMT compression couplings?
UL 514B Table 35.1: ½ in EMT = 150 in-lb, 1 in EMT = 250 in-lb. Always verify with a calibrated torque wrench.
Does EMT act as an equipment-grounding conductor?
Yes—steel EMT with tight fittings qualifies under NEC 250.118(4).
Are Conversions Tech compression fittings concrete-tight?
Yes. Every connector and coupling is stamped “CONCRETE-TIGHT / RAIN-TIGHT,” ready for slab or rooftop installs.
AC Disconnect Switches
Why does every outdoor condenser need a disconnect?
NEC 440.14 demands a readily accessible disconnect within sight (≤ 50 ft) so techs can safely de-energize the unit.
Fused vs non-fused AC disconnect – how do I choose?
Use a fused model when MCA exceeds breaker rating or higher SCCR (up to 100 kA) is required; otherwise a 60 A non-fused unit is standard for residential HVAC.
What wire sizes fit a 60 A Conversions Tech disconnect?
14 AWG–2 AWG Cu/Al; torque lugs to 45 in-lb.
Is back-feeding allowed?
No. Knife-blade contacts are not rated for reverse feed and doing so voids UL listing.
Weatherproof Boxes & Extra-Duty In-Use Covers
“Weatherproof” vs “damp-location” boxes – what’s the difference?
Weatherproof boxes withstand direct rain; damp-location boxes are protected under awnings or overhangs per NEC 406.9.
When is an extra-duty in-use cover required?
Every 15 A or 20 A, 125/250 V receptacle in a wet location must have an extra-duty cover even while a cord is inserted.
What makes a cover “extra-duty”?
It must hinge ≥ 90° after installation and resist impact; “EXTRA DUTY” is embossed on the lid to comply with NEC 406.9(B)(1).
How many #12 conductors fit a 22 cu in weatherproof box?
NEC 314.16(B): nine conductors max (22 ÷ 2.25 cu in per #12).
Can I bury a weatherproof box?
Only if listed NEMA 6P for direct burial; otherwise keep it ≥ 6 in above finished grade.
