When can flexible conduit be used?
It is mainly used where rigid catheters are difficult to bend because flexible catheters can bend. Although flexible conduits are easier to work with than rigid conduits, it offers less protection for the conductors it carries.
Is XHHW better than THWN?
Hospital Grade (low leakage insulation) Dual Rated 600V/1kV. Uses XLPE (cross-linked) Insulation Instead of PVC. Substantially Higher (better) Insulation Resistance….HOW TO KNOW THE DIFFERENCE.
| THHN/THWN-2: | XHHW-2: |
|---|---|
| HH = High Heat Resistant | HH = High Heat Resistant |
| W = Water Resistant | W = Water Resistant |
