    I've got my main water supply, galvanized 3/4in, that has a large bonding wire clamped to it. It runs across the unfinished basement, and ties into the electrical panel. I'm planning on replacing my old galvanized plumbing with PEX. I understand my main panel needs both a ground rod, which is...

    Hi there! We just posted a new article on this topic of swimming pool grounding and bonding. We cover the basics of each (they are not the same) but the end story is basically that this is normally required to NOT be a DIY project and most local electrical codes require licensed electricians to...

    When is a bonding bushing required? See picture attached. Should I use a plastic bushing or a bonding bushing in this situation? Three #4 wires and one #8 wire (for ground) are entering a subpanel through 1" PVC conduit with a PVC male adapter and a locknut. Thanks

    (note: also asked on stack) What I am looking for is guidance and honest evaluation. I'm not afraid of being wrong. I want to save some bucks and learn some things, without blowing myself up. So please tell me if I'm doing something dangerous, and preferably please tell the section of the...

    Our electrical panel was bonded to our copper cold water pipe, but then we had some pieces of PEX installed. There is PEX now on both sides of the water meter. Our side, and the service side. This certainly must block the continuity. So, is there any reason at all to leave the bond there?

    In a 1953 14-2 wired home, an updated 100 amp panel has been installed with a braided copper ground wire running from an outside buried copper rod. No other bare ground wires are attached to the section where this Main Ground is. I have run a single 14 awg wire from that section to a junction...

    My house has corrugated stainless steel tubing (csst) for the natural gas system, and csst seems to have some vulnerability to lightning strikes. Specifically, a lightning strike can occur *near* your home (not on your home) and “energize” the underground natural gas system. The electricity...

    I've done lots of work on my house, including new drywall. The texture is a smooth finish. After sanding, I've vacuumed the walls, sponged them, then dusted with a dust mop. No dust is visible on my finger when I check it. But no matter how fancy a PVA primer I buy, the finish coat bond is weak...

    I would like to install ceramic tile over an old terrazzo floor. Floor is original to house (Florida mid-60s). I understand there are some required preparatory steps needed before applying thinset and tiling but I would like some further input if anyone has first-hand experience. From what...

    House built in '04. I have an natural gas 1" black pipe that comes in the house from the meter. Then there is a 1" X 1/2" X 1/2" Tee. Off the Tee is 2x 1/2" CSST lines. One line goes to a regulator and manifold on one side of the house to supply the furnace, water heater, and range. The other...

    So, I've been searching and searching for an answer to this one, but haven't found anything definite (i.e. backed up by code) yet. I've seen it done before where, in a metal box, instead of pigtailing all the grounds together and then attaching to a ground screw, someone pigtailed half of them...

    Hi All, I've read previous threads about bonding Black Pipe and CSST to the Service Entrance. I WILL call my utility company to find their preferred method as in the end most threads point to that. Background : Had new gas service meter installed for a "professionally" installed gas log set...

    Thank you in advance for your help. I am installing a new 220 volt Hot Tub in my backyard on a concrete slab. To power the tub I am utilizing a previously discarded 220 volt circuit. This circuit was previously used to supply an electric range. The range was long ago converted to gas and...

    Hi, I have a 125 amp subpanel that was previously used just to power a furnace and air conditioner. When we remodeled our kitchen, the electrician tapped into this box (in the basement) to add 4 new circuits to the kitchen. The problem is that there is only 3 wire cable feeding the box (2 hots...

    Proper Water and Gas line bonding. Sub Panel OK? I live in a home built in the mid 60s. Originally there was only a fuse panel located within a clothing closet and all outlets/fixtures were connected with two wire NM with no ground. At some point a panel was added outside to accommodate an...

    I have what I imagine is a very basic question, but I haven't been able to find reliable information & instruction. Installing a hottub, and have completed the wiring. 50a breaker in the main panel. 4 THHN 6awg wires (3+Ground) running to this GFCI load center. Wires are run in RNM conduit...

    I just came across DIY Chat - it looks like a great place. I've searched around but cannot seem to identify what the rules are regarding a neutral path between two primary panels so I thought I would post my question. Here is my situation: I have 400 amp service (1 meter) (maybe 320 amp - I...

    Hi, I have recently purchased a used hot tub that I am going to install on my back patio. I have the 50 amp GFCI disconnect in place, 1-1/4" PVC conduit run to near where the tub connections will be and will transition to 1" liquidtight flexible conduit for the tub entrance all the way to the...

    where my water line comes in the basement I have my service panel bonded to it right where it comes in... then it goes to a water metere, then a check valve then they have the same bonding line clamped on the other end of the meter and check valve also (I guess to reduce resistance past the...

    My pool is semi-inground. I know now that it should be bonded. Do I need to dig down all around the pool and attach the #8 copper wire at the base or can I attach it at the top of each post under the caps and string it around that way?
