Use of TradeHub.tools
TradeHub.tools provides calculator tools, field workflow references, and code or standard reference pages for informational use by trade professionals, estimators, contractors, technicians, designers, students, and other users. The site is designed to support field screening and planning decisions, not to issue final construction approval or replace professional review.
All results depend on the information entered by the user, the assumptions selected in the tool, and the scope described on the relevant calculator or reference page. Users are responsible for reviewing the inputs, understanding the result boundaries, and deciding whether the output is appropriate for their project context.
1.1 Electrical Calculators and NEC References
Electrical tools and resource pages reference published NEC topics and TradeHub source-alignment records where applicable. These tools may help screen load, breaker, conductor, ampacity, voltage drop, raceway fill, box fill, and EV charging conditions, but they do not provide final electrical design, installation approval, inspection approval, utility approval, or AHJ approval.
1.2 HVAC and Mechanical Calculators
HVAC tools support screening around Manual J®, Manual S®, and Manual D® style workflows. They are not a substitute for complete HVAC design, commissioning, equipment documentation, airflow verification, duct leakage review, refrigerant setup, combustion safety review, or licensed contractor judgment.
1.3 Resource Pages
Resource pages summarize selected code or standard topics in plain language for field reference. They do not reproduce full code books, standards, listing documents, manufacturer instructions, local amendments, permit requirements, or inspection interpretations.
1.4 Areas in Review
Some trade areas, roadmap items, or reference queues may be shown as in review or planned for later development. Those references are informational only until a live tool or resource page is published and clearly marked as available.
Calculator and Reference Use Scope
TradeHub.tools results are field screening and reference outputs based on user-provided information.
TradeHub.tools does not provide professional engineering, architectural, electrical contracting, mechanical contracting, permitting, inspection, legal, or AHJ approval services. Calculator outputs and reference pages are generalized aids and must be reviewed against the actual installation, adopted code cycle, local amendments, utility requirements, manufacturer documentation, listing instructions, and site-specific conditions.
Before construction, installation, repair, equipment selection, or permit submission, users should verify results with the appropriate licensed professional, responsible contractor, manufacturer documentation, utility requirements, and the Authority Having Jurisdiction.
Professional Verification and Local Code
The adopted code cycle, local amendments, site conditions, utility requirements, manufacturer instructions, equipment listings, permit requirements, and AHJ interpretation control over any generalized calculator or reference output.
Search descriptions, page summaries, state or region labels, and workflow text are provided for navigation and field context. They do not create a project-specific determination and do not override applicable code, standards, manufacturer instructions, or local enforcement requirements.
User Inputs and Result Accuracy
Users are responsible for entering accurate information, selecting the correct tool settings, reviewing the result explanation, and confirming that the calculator scope matches the field condition being evaluated.
TradeHub.tools may include warnings, scope notes, field boundaries, and handoff links to related calculators or reference pages. Those notices are intended to help users understand result limitations, but they cannot identify every project condition, product requirement, local amendment, or inspection requirement.
No Warranty
TradeHub.tools is provided on an informational and as-available basis. Greenspark.Group LLC does not warrant that any calculator, reference page, source summary, workflow link, or result output will be complete, error-free, uninterrupted, current for every jurisdiction, or suitable for a specific project.
To the fullest extent allowed by applicable law, Greenspark.Group LLC disclaims warranties of accuracy, completeness, merchantability, fitness for a particular purpose, non-infringement, and uninterrupted availability.
User Responsibility and Acceptable Use
Users are responsible for how they interpret and apply TradeHub.tools outputs. Users agree not to misuse the site, attempt to bypass security controls, interfere with service operation, submit malicious content, or use automated activity that burdens the site or degrades access for others.
Users should not scrape, copy, reverse engineer, bulk extract, or systematically reproduce TradeHub.tools content, calculator logic, interface patterns, data structures, or workflow materials without permission. Greenspark.Group LLC may restrict access for abuse, automated scraping, security risk, or misuse.
Intellectual Property
TradeHub.tools page layouts, calculator interfaces, explanatory text, source-scope summaries, workflow organization, original examples, and site design are owned by or licensed to Greenspark.Group LLC, except where third-party trademarks, code references, standards names, or public source references are identified.
References to NEC®, ACCA manuals, Manual J®, Manual S®, Manual D®, manufacturer instructions, or other standards are used for source identification and field context only. TradeHub.tools is not a substitute for the official publications or documents issued by the relevant standards organizations, publishers, manufacturers, or authorities.
