Thought I would share some of the topics of discussion from a 3HR. CEU electrical class presented by a Electrician/Home Inspector.
FPE - The problem that was discussed was at the back of the bus bar there was significant scorching. This wouldnt be visible until the panel was removed.
SEC can not be spliced inside the panel box. Need to look for cracks at the exterior SEC located at the mast head. Older cloth insulation doesnt have Ultra violet protection. **(Both of these I didnt know)
**A new inspector was writing up all the spliced connections in the panel box. (The NEC has a long drawn out code for this one) One ispector said if you cant see the nuetral bar it is to overcrowded.
All knob & tube shall be reconnected on 15 amp circuits. This is for the re-wire code.
This electrician says that the low voltage Transformer & the receptacle below the main panel can be double lugged at the breakers. **(Man I have heard so many opinions on this)
**5) Ok I will need clarification on this. The NEC changed that the nuetrals & grounds in the main panel are on seperate bars. Before this change there can be Example. 14 gauge ground connected with a 12 gauge nuetral resulting in a loose connection.
HVAC guy harrasing the electrician.:mrgreen: HVAC says that a home with an electric furnacedraws a 120 amp load and if the home has a 100 amp service can result in some issues???
To help indentify aluminum solid wiring the sheathing will have a green color. The problem with this type of aluminum is the connections at the switches/receptacles. Need cop/alum connectors.
**My questions from the seminar for clarifications are. **
What the heck is a (LOOM-Double cover) did I even spell this right.
There was a discussion that the SEC needs to be 8 feet above the ridge of a roof. I thought it was 3 feet.
Besides square D what other breakers are allowed to double tap?
The best info was that the electricain said that the illistrated guide to electricla code is the reference book to have.
There was a lot of discussion on meter bases. He advised to contact the local city.
He also stated that each city can be different where the same city can have different inspectors that can differ. **EXAMPLE. **General rule. Each room needs at least 2 wall receptacles on opposite walls or as otherwise permitted by local inspection authority ect…
Sorry post is so long. Want to share with less expirenced inspectors.
Cant wait for Paul A. 8 hour seminar in Cleveland. I have at least one newer inspector that plans on attending.
