I have seen inspectors require work that had been covered up before inspection to be fully exposed to allow inspection. All the cabinets and drywall needed to be removed from the kitchen. The inspector does not have the luxury, nor should my taxes pay for them to educate the uninformed. Sorry that someone's mistakes are costing you.

The NEC allows exposed PVC conduit. It can go into a panel.

In addition there is a limit of six foot of flexible conduit. Why didn't they come out under the spa skirt?

The CEC might have different box fill rules.

There was power in, power out on one side of the switch with the device making the splice instead of a wire nut. The other connection was the switched hot. Nothing at all unusual, but many would consider it less than optimal practice to use the backstab as a splice.

I agree that no bonding would be needed with the plastic pipe. I could also make the same claim even with copper feeding the tub since it is not touching the circulating water.

The Jack, the tubs I have seen have plastic piping under the skirt for the circulating water to pass through. Do you still see the need for the motor to be bonded? The metal is not in contact with the circulating water. It is on the supply side. Once the tub is filled it is no longer touching the metallic pipes.

Article 250.114 also needs to be considered. 250.114 Equipment Connected by Cord and Plug. Under any of the conditions described in 250.114(1) through (4), exposed, normally non?current-carrying metal parts of cord-and-plug-connected equipment shall be connected to the equipment grounding conductor. (3) In residential occupancies: a. Refrigerators, freezers, and air conditioners b. Clothes-washing, clothes-drying, dish-washing machines; ranges; kitchen waste disposers; information technology equipment; sump pumps and electrical aquarium equipment c. Hand-held motor-operated tools, stationary and fixed motor-operated tools, and light industrial motor-operated tools d. Motor-operated appliances of the following types: hedge clippers, lawn mowers, snow blowers, and wet scrubbers e. Portable handlamps Installing a GFI still would not comply with this section.

The maximum is 360 degrees of bend in the run between access points. The encased conduit would be considered outside the building if there was a minimum of 2" of concrete over them. This would allow for the unfused conductors to enter a panel not on an outside wall of the house. However, I would not consider what is shown to meet those requirements since not all the conduit is covered.

Voltages can look normal, but when placed under a load you see a variation if you have a failing connection.

How funny would it be with 15 other people? Inquiring minds want to know.

What's your reference source? There's no such rule in the NEC. I agree with Jim K. I would also like to hear why you think this is such a shock hazard.

Thanks Doug, maybe I should have seen his smirk in his avatar. []

The disconnect may be as simple as a single or double pole toggle switch, a pullout disconnect, 6 throws or less or a main breaker. The NEC has required this for as long as I can remember. Why a labor organization would have an exception to a code escapes me.

Here is a link to some of those. http://www.legrand.us/adorne/select/out ... p1OQsRvGa8

Square D only lists their own products in their panels. Was the knockoff classified for use in a Square D panel?

As long as the switch is outside the footprint of the tub or shower there is no NEC issue. I don't see why some get so worked up about this. I have used a switch with wet hands plenty of times and never seen or heard anyone having an issue. The plastic is not conductive. Also not all lights and fans are prohibited above the shower. Only hanging or cord connected types. Surface and flush mounted are fine.

Once you get rid of the K&T you can have your house insulated and cut your energy bills. I rewired an entire house except for a few ceiling mounted lights and switches. The rest was all new with no damage to the walls.

Agreed, the POCO can do what they want. They use different criteria to size their conductors.

If the detached structure is feed by a single circuit it does not require a grouding system. A MWBC is one circuit for this example.

A three wire feeder installed before the adoption of the 2008 NEC was allowed provided no other metallic path was between the buildings. The neutrals were again re-bonded like a service panel. The 100 amp rating is the maximum that it can be supplied by.

Watts are watts, regardless of the voltage. It would cost the same to operate. Ampacity and the required wire sizes would be smaller at 240 volts due to the reduced ampacity.

That is an Arlington box. They come with a standard GFI plate to finish off the install. Yes, a trim plate is missing.

If the panel is only fed by 3 wires it should be bonded the same as a service panel. If so it would not matter which bus the grounds landed on. I still think I see a green bond screw above the 4th white wire from the bottom right.

Looks like a green bond screw on the right side bus under the white wires. The panel label should show the location of the bonding means.
