Flame arrestors caption MESG; never generate an inspector

explosion-proof-housing-oem already captioned Class/Division. This is the in-line flame-arrestor element: caption MESG and NEC group as authored type. Do not generate a talking inspector or a flame path Veo cannot certify.

A specifier who pauses on this listing is matching an element: crimped ribbon, element diameter, the housing you tooled, the gap you actually tested. Maximum Experimental Safe Gap and the NEC group are numbers from a datasheet. They are not a cinematic fire, and they are not a constructed inspector walking the code. Photograph the element. Stamp MESG and group after picture lock. Leave the flame off the generate.

The element is this SKU, not the enclosure page

Explosion-proof ads caption Class and Division; never generate a talking inspector already owns the box: flame path of the housing, joints, window, Class / Division / Group on the skirt. Do not rewrite that post as an in-line arrestor. Do not crop a Type 4X brick and prompt “now it is an element.” Specifiers can tell.

Photograph the unit on the bench or in an empty bay you own — element visible, nameplate in frame if the silk is already true. The AI product video generator is the door when the job is this object, moving: reference rows that hold a real object’s shape while the shot moves. Prompt only the camera. A slow push along the element face. Do not prompt “an in-line flame arrestor in a busy plant, inspector explaining MESG.” That sentence is how the element becomes a stock fitting, a fire, and a mouth you did not hire.

If the still would fail a distributor audit — wrong diameter, extra hub, a colourway you do not stock — stop. Reshoot. A generated arrestor that looks Group C and is not is a claim. Do not generate a flame path the camera never saw. A map is a legal drawing. The element is the listing.

MESG and NEC group are authored type

MESG is a millimetre figure from a test you already ran or cited. NEC group is a letter on the sheet — A through G as your listing actually states. Those strings are the product. Video models do not typeset them. Image models will try; they will also invent a digit. A 0.65 mm that becomes 0.90 for six frames is a scrap part on a feed. A Group D that flickers to B is a different atmosphere.

Add a text overlay burns one authored string, whole clip, top / center / bottom. Optionally font size, color, background. It does not transcribe. It does not listen. “MESG 0.65 mm / Group C” is overlay copy, not a prompt adjective. Offers and ratings change by catalog row. Copy lock can be later than picture lock.

If someone said the MESG on a take of a real named engineer, add captions transcribes that speech — styled, burned in, speech in. A mute element has nothing to transcribe. Overlay is the rating on a silent arrestor. Captions are not a way to invent a lecture the file never contained.

Do not overlay before you crop. Do not prompt the video model to “show MESG on the element.” Invented group is a listing miss. If the silk is already legible and matches the catalog, keep it. Do not treat Veo as an AHJ.

No flame path Veo cannot certify

A flame in frame is not proof the element quenched. Specifiers buy the element, not fire. Motion is a slow orbit of the approved still, not invented vapor. Veo 3.1 is native audio, 4 / 6 / 8 seconds, 4K, 40 credits. It will invent a prettier flame. That flame is not a certificate. No catalog row can certify a path. If the brief needs a drawing, scan the one you already sealed.

Manufacturers is plant-floor scale, QC, recruitment. It is not a MESG board. Electricians is the install crew: “don’t DIY this,” anonymized hazard finds. That page is not an OEM flame-arrestor catalog. Do not rewrite /for.

Never generate a talking inspector

A constructed inspector walking MESG, NEC group, “what you should install on this vent,” or a code interpretation is a legal-adjacent persona. Synthetic presenters on health and finance are a YPP kill names AI personas that present as human experts on legal issues as well as health and finance. Hazardous-area and arrestor selection is that shape. Labelling the face AI does not leave the bucket.

A silent element is not that shape. A real named engineer on camera is a different day — then you caption that take. Generation can still do the part. It cannot be the code. Do not VO the MESG over a flame the model invented.

Order: element still; product-video motion if needed; overlay MESG and group after crop; captions only if a real person spoke.

FAQ

Can Veo letter MESG on the real element if I upload the still?

Do not treat Veo as a typesetter. Glyphs it adds are invented ratings. A flame path in the prompt is a hazard you did not measure. Upload the element still for motion if you must, then burn overlay for MESG and NEC group.

Is add-captions the same as overlay on a silent arrestor?

No. Add captions transcribes speech. Add a text overlay stamps a line you wrote. A mute element has nothing to transcribe. The MESG is authored type unless a real named person said it on camera.

Why not put an inspector on camera in the same generate?

A constructed inspector prescribing classification is a legal-expert talking head. Manufacturers is the plant page. Electricians is the crew page. This page is the in-line element plus authored MESG and group. Two jobs. Two files. No generated flame path.

Is this the same job as the explosion-proof housing post?

No. That post is the enclosure: Class, Division, Group on the box, no talking inspector. This leftover is the in-line flame-arrestor element: MESG and NEC group as type you wrote. Do not restage the housing as an element, and do not add a flame so the rating “looks industrial.”
