Purchase this book to use when taking my Idaho and DC masters HVAC licenses
When your jurisdiction uses an older codebook eBay’s place to find it. Thank you eBay for saving me a ton of money.

The trade union training arms publish the best trading materials bar none.
I served my apprenticeship with the sheet metal workers international association. We have the best training materials on the subject. I apply this knowledge to the other trades.

Good help on understanding the code
As a sheet-metal service technician with the electrical license this book helps me understand the code better to apply to my corner of the trade.
