Abstract

A system comprises a passthrough installed on a roof deck. The passthrough includes a base with an aperture, and a lid attached to the base. The aperture of the base is configured to align with an aperture formed within the roof deck. The system includes at least one cable and a grommet installed on the at least one cable. The lid and the base are configured to compress the grommet around the at least one cable.

First claim

What is claimed is:

1. A system, comprising:

a passthrough installed on the roof deck, wherein the passthrough includes
a base having
a first end and a second end opposite the first end,
a first surface extending from the first end to the second end,
a second surface opposite the first surface,
an aperture extending from the first surface to the second surface, and
a plurality of first cavities,

a lid attached to the base,
wherein the lid includes
a first end substantially aligned with the first end of the base, and

a plurality of second cavities,

a sidewall between the base and the lid,
wherein the sidewall includes
a first end, wherein the first end of the sidewall is proximate to the first end of the base, and
a plurality of apertures,
 wherein the plurality of apertures of the sidewall is located at the first end of the sidewall,
wherein each of the plurality of first cavities and each of a corresponding one of the plurality of second cavities are sized and shaped to form a corresponding one of the plurality of apertures,

wherein the first surface is juxtaposed with the roof deck, and
wherein the aperture of the base of the passthrough is configured to align with an aperture formed within the roof deck;

a plurality of cables,
wherein each of the plurality of cables includes a first end and a second end opposite the first end of the cable,
wherein each of the plurality of apertures of the sidewall is sized and shaped to receive a corresponding one of the plurality of cables; and

a grommet installed on the at least one plurality of cables proximate to the first end of each of the plurality of cables,
wherein the grommet is located between the plurality of first cavities and the plurality of second cavities,
wherein the grommet includes
a plurality of openings sized and shaped to receive a corresponding one of the plurality of cables, and
a plurality of sections, wherein each of the plurality of openings is located in a corresponding one of the plurality of sections,
wherein each of the plurality of sections of the grommet is located between a corresponding one of the plurality of first cavities and a corresponding one of the plurality of second cavities,

wherein the lid and the base are configured to compress the grommet between the plurality of first cavities and the plurality of second cavities and around the plurality of cables when the lid is attached to the base,
wherein the aperture of the base of the passthrough is sized and shaped to receive the plurality of cables, and
wherein the first end of each of the plurality of cables extends outwardly from the first end of base and the first end of the lid of the passthrough.

2. The system of claim 1 , wherein the lid is removably attached to the base.

3. The system of claim 1 , further comprising a photovoltaic module installed on the roof deck, wherein the passthrough is installed proximate to the photovoltaic module.

4. The system of claim 1 , wherein each of the plurality of cables includes an electrical connector, wherein each of the plurality of apertures of the sidewall is sized and shaped to receive a corresponding one of the electrical connector of the corresponding one of the plurality of cables.

5. The system of claim 1 , wherein the base of the passthrough includes a tubular member extending from the first surface, wherein the tubular member includes the aperture of the base, and wherein the aperture of the roof deck is sized and shaped to receive the tubular member.

6. The system of claim 5 , further comprising a receiver attached to the tubular member.

7. The system of claim 5 , further comprising an electrical box installed underneath the roof deck, and wherein the electrical box directly receives the tubular member.

8. A cable passthrough, comprising:
a base having
a first end and a second end opposite the first end,
a first surface extending from the first end to the second end,
a second surface opposite the first surface,
a plurality of first cavities, and
an aperture extending from the first surface to the second surface;

a lid attached to the base,
wherein the lid includes
a first end substantially aligned with the first end of the base, and
a plurality of second cavities; and

a sidewall between the base and the lid,
wherein the sidewall includes
a first end, wherein the first end of the sidewall is proximate to the first end of the base, and
a plurality of apertures,
wherein the plurality of apertures of the sidewall is located at the first end of the sidewall,
wherein each of the plurality of first cavities and a corresponding one of each of the plurality of second cavities are sized and shaped to form a corresponding one of the plurality of apertures,

wherein the cable passthrough is configured to be installed on a roof deck such that the first surface is juxtaposed with the roof deck, and
wherein the aperture of the base is configured to align with an aperture formed within the roof deck,
wherein the cable passthrough is configured to receive a plurality of cables,
wherein the aperture of the base is sized and shaped to receive the plurality of cables,
wherein the plurality of cables is capable of extending outwardly from the first end of the base and the first end of the lid of the cable passthrough, and

wherein the lid and the base are configured to compress a grommet installed between the plurality of first cavities and the plurality of second cavities and around the plurality of cables when the lid is attached to the base,
wherein the grommet includes a plurality of openings sized and shaped to receive a corresponding one of the plurality of cables, and a plurality of sections, wherein each of the plurality of openings is located in a corresponding one of the plurality of sections, wherein each of the plurality of sections is configured to be located between a corresponding one of the plurality of first cavities and a corresponding one of the plurality of second cavities.

9. A system, comprising:
a passthrough installed on a roof deck, wherein the passthrough includes
a base having a plurality of first cavities,
a lid attached to the base, wherein the lid includes a plurality of second cavities, and
a sidewall between the base and the lid, wherein the sidewall includes a plurality of apertures, wherein each of the plurality of first cavities and a corresponding one of each of the plurality of second cavities are sized and shaped to form a corresponding one of the plurality of apertures;

a plurality of cables,
wherein each of the plurality of apertures of the sidewall receives a corresponding one of the plurality of cables; and

a grommet installed on the plurality of cables, wherein the grommet is located between the plurality of first cavities and the plurality of second cavities, wherein the grommet includes
